Homemade Gak

Homemade Gak! This is the cheapest and best kid entertainment ever!! Recipe on { lilluna.com } Supplies needed include - glue, borax, water, and food coloring!

With it being Summer here in AZ, things are getting pretty HOT, and the kids aren’t as excited to play outside, so I thought it would be fun to make Homemade Gak – aka Slime (It’s something I made all the time with my cousin growing up!)

The recipe that was most similar to the one I used growing up is one I found HERE. It is so EASY and literally takes 2 minutes to make, but has provided HOURS (and I’m not even joking!), HOURS of entertainment!! Every day, for a week now, the kids have played with this gak for at least an hour each day. I’ve pulled out plastic cookie cutters and they go to town, and guess what?! I LOVE it!! It’s hardly any mess!!

Here is how you can make DIY Slime/Gak as well!


– TWO 4 oz. bottles of Elmer’s Glue

– 1 tsp. Borax (found in the laundry detergent section of the store)

– Water

– Plastic Cup

– Bowl

– Food Coloring

3. Add some food coloring. I got Betty Crocker Neon Gel Food Colors and they worked FAB!! The Neon made it look awesome, but I ended up squeezing almost half the tube into the mixture because I wanted it to be really bright. ๐Ÿ™‚ Set aside.

4. Add 1/2 cup warm water to your cup. Add 1 tsp. borax to the water and mix until borax dissolves. Then pour this into your glue bowl. Start stirring and you will notice how it starts becoming stringy. Keep mixing by using your hands and squishing around. You will notice after a few minutes that it has become prettyย gelatinous.

DIY Slime/Gak - takes a minute to make and provides hours of entertainment!

5. Let the kids play with it for a bit and it will become the perfect GOOEY consistency!

So fun and so easy!! We have also made purple since and have pink gak in the line-up!

This is seriously the best homemade craft/project I’ve done with the kids in a long time. It doesn’t smell and get all over like other gooey substances and it’s so fun to play with! PLUS, it is super cheap to make!

Gotta love cheap entertainment! ๐Ÿ˜‰

    1. Thanks, Miss Jen!! You’re so sweet!! Your kiddos will love it! Let me know if you give it a go. ๐Ÿ™‚

    1. LOL!!! You’re too nice, Kelsey!!! I try to do fun things with the kiddos to help us both stay sane – haha!

  1. FYI- If you use clear elmers glue (usually right by the normal white kind) it doesn’t take near as much coloring to make it brighter! It works great.

    1. LOL!!! My kids love the funny noises. And they love when I make bubbles with it pressing it up against my mouth – haha!!

      1. I tried to make this I followed the directions correctly but mine is like a hard ball, it wont stretch, it pulls apart. What dii do wrong? Help please ๐Ÿ™

          1. I would just keep working at it until it is smooth… it takes several minutes to work on it. And I’ve made it once or twice where there was excess water. Not sure why I had it that time when I haven’t ever had it before.

        1. Not sure if you will see this, but I just did the same thing tonight. I split the recipe in half to make 2 different colors, one for each kid. The first one came out great, but the second one was a hard ball that we couldn’t do anything with.

          Here is what I think I did wrong, I forgot to stir up the food coloring and water into the glue and added the borax. I think I added a little bit too much borax too, so I am going to make sure that I am very careful with that next time, and then make sure I mix everything up good. I was just in a hurry to get the second one done for my son to play with and in the end, my daughter split hers in half to share with her brother(with no prompting from me, so I am happy).

          1. Thanks for the comment, Amber and sorry the second batch didn’t turn out. I would definitely be sure to mix it all up well and use the exact measurements for the borax. Hopefully, that will help next time. PS – So sweet your daughter shared. ๐Ÿ™‚

  2. I love Gak. When I taught preschool I used to make it all the time for the kids. So far my little one is still putting everything in her mouth so I’m going to have to wait a little while before I give it a try with her.

    1. Yeah, unfortunately I’ve found some in my 1 year olds mouth but the 2 and 4 year old love it! ๐Ÿ˜€

    1. Thanks, Amanda! I know your girls will love it!! We made pink and purple in the last week (my daughter’s fav colors) so she’s been having a ball with “her” gak. LOL! ๐Ÿ˜€

  3. You have very great ideas, Iโ€™m glad to stop on your blog and learn so many things about itโ€ฆ I do appreciate this simple but worthy. It motivates me to do the rest effectivelyโ€ฆ

  4. We just made purple Gak and my daughter is the happiest 8 year old ever!Seriously! :)Thank you so much for this!I love your blog! ๐Ÿ™‚

      1. I did! I can’t stop playing. My wife thinks I’m crazy. I even packed some into a ballon and it made for a nice little stress ball. Popped it though. Will make another one soon ๐Ÿ™‚

  5. Thank you so much for this! I just made it with my 3 year old but I must of done something wrong….it almost crumbles instead of stretches. Could it be because I used the clear Elmers? So I can do it right next time ๐Ÿ™‚

    1. Hi Tiffany!! So sorry about the gak. I have no idea why it crumbled. I have never used the clear Elmer’s and only the white and have never had issues. If you try it again with white and it works fine, let me know, so I can be sure to let other readers know about the problem too. ๐Ÿ™

      1. I’m getting some more glue at the store today, I also want to try the bouncy ball recipe! I’ll let you know if it worked out this time. My 3 year old loved to play with it anyway though ๐Ÿ™‚

    2. Hi Tiffany,
      I have made this several times. It always turned out and then all of a sudden, each batch was crumbly. I realized that I was not mixing the glue and water before adding the borax. I was just dumping all of the ingrediants in. The trick is to mix the glue, water and food coloring WELL, before adding your 1/2 water with borax. Also make sure all of the water is very warm.
      Good luck!

  6. Please remember that Borax is TOXIC and have your children wash their hands when they’re done playing with it ๐Ÿ™‚ we are gonna stick to regular ole salt dough!

      1. Do you think it would be possible to substitute Borax with something non-toxic to achieve the same/similar consistency?

    1. Just in case this might be of interest – the Material Safety Data Sheet – one of those official study lists – labels Borax as a health hazard rating of 1. This is the same rating given to salt and baking soda. It is non-carcenogenic, it does not penetrate the skin well, and it is not bio-accumulative. In short, from my personal experience and study, this would not cause any health hazard for Gak lovers. ๐Ÿ™‚ Hope this helps.

      Thank you for a fun idea for my kiddos that I had forgotten about. They will rise up and call you blessed. ๐Ÿ™‚

    2. Borax is no more toxic than salt or baking soda!!!!!!!! Just don’t ingest large quantities. Sometimes Borax is confused with boric acid, which is more toxic.

    3. We made this for my son’s mad scientist birthday party, but instead of Borax we used equal parts liquid starch, Elmers glue and water. It worked great and no worries about anything toxic.

    1. You know what, they weren’t at all!!! Here’s the sad thing… I got the Neon Food Coloring. We made neon green and a few days later neon purple. Then, we decided to make hot pink. It was my hubby’s grandma’s funeral and my mom came to watch the kids for us, so I wanted to make a fresh batch of gak to entertain the kiddos. I was running behind and asked the hubby to finish it off for me. Well, he did but it turned his hands hot pink!! And we were headed straight to the funeral and he couldn’t wash it off. I felt so bad!!! He thought I knew it stained but the green and purple hadn’t. Makes me wonder what color you did and if only certain colors stain. So sorry about that!

        1. Thanks for the tip. My grandkids and I didn’t mix it with water first. We made neon purple and neon blue. the kids have beautifully colored hands. We’ve scrubbed a few times with Dawn and it did take most of it off but they still looked stained and they have school tomorrow. Their teachers will know their crazy Mimi( they know me as I’m a retired teacher) is at it again. lol

          1. Hi Cheryl!! So sorry about that. I have a feeling that any dark color will do that so to prevent stained hands I would try lighter colors. We made purple but it only lasted on our hands for a few hours.

  7. Hi I recently discovered your website and love it! I am trying to be more creative with fun projects for my boys (ages almost 4 and 1). I love being at home with them and I love creative projects, I just need someone to help give me ideas, lol! And I’ve learned I need to plan ahead better (have all the supplies on hand and set aside time to do it). My 3 year old and I just made the Gak (blue his favorite color) while my 1 year old nap and it has been over and hour and he is still playing with it! Thanks! I look forward to more fun ideas!

  8. I made this today for my son. It was so simple and quick. I can’t wait to do this again with his cousins, and possibly next year at his birthday party for an activity and a take-home gift for the kids!!

  9. Ok We just made this and it is extremely messy! We did everything you did, but maybe it needs more borax? I’m gonna try that next time. It just clings to our hands rather than like the store bought which is more solid. Fun though, if I can get it to turn out right! Thanks!

  10. This is awesome!! We just made some and it came out great!! Question.. Does it store well? Can you use it a week later or is it a one and done?


    1. Hi Kristyn- This does store well, btw. I am glad to see you post this. I posted this back in 2009 – link : http://mygratitudeattitudes.blogspot.com/2009/01/making-glurch-creative-play-for-kids.html
      And it was amazing how much “crap” I got from people. It was posted on another big kids website too back in 09, and the rude comments were unbelivable.. I even posted the same link as you- Steve Spangler Science. People were very concerned about the Borax. There is the tiniest bit of Borax, which is not as toxic as everyone believes. It is toxic if you pour it in your eye. I personally would be more concerned about the children eating the glue. lol. But in all my years of teaching, and making this with children from preschool to 2nd grade, I have never had a child once try to ingest this. It is a fun “science” project. We use Borax to clean everything at hour house. It is laundry soap, not the stuff you kill bugs with – that is totally different- and I think people get very confused. Sorry for my little “rant” but I just wanted to thank you for the repost. It is a super fun summer activity. It will store for several days also- but usually it is a one time thing at our house. ๐Ÿ™‚ Thanks for sharing so much fun stuff! -sharla

      1. Thanks for the note, Sharla! We have made it several times and I have yet to see any of my kids ranging 1 – 4 try to ingest it. We love it and will continue to make it. ๐Ÿ™‚

  12. I let all the daycare kiddos make their own today, it was a huge hit! Even the older kids who get bored easily loved it! Thanks for the wonderful, and inexpensive idea!

  13. I just made this for my daughter to play with and I disappointed with how it stains anything it touches (due to the food coloring). I don’t want to skip out on the color (that’s part of the fun!!!), but I also don’t want my nice couch, clothes, walls, etc. stained to high heaven. I didn’t use the Betty Crocker brand food coloring b/c I already had some McCormick neon coloring. It’s the regular kind of coloring-liquid, not gel.

    I did read in the comments about your hubby’s hands getting stained with the pink… that is the color I tried. I will try another color next time (I only had enough glue for one batch) and see, but I was just curious if you’d heard from anyone else about this and found a solution ๐Ÿ™‚ Seems strange that it would be a “pink only” thing…


    1. Hi Heather! Thanks for the comment. I have no idea why the pink stained. We have made purple, red, green and orange with the neon gel colors and none of those stained – only the hot pink. Still haven’t heard a solution for the colors, but will let you know if I do. Sorry about that. ๐Ÿ™

      1. I’m so sorry, Sandy. I haven’t had anyone have this problem before. I have made it countless times now and have never had this issue. :/

  14. Just made this today after pinning it on Pinterest a couple weeks ago. It works great! We do get a few clingy pieces, but no one seems to mind. I don’t have any food coloring so ours is just plain ol’ white. Thanks so much for sharing the recipe! I can’t wait to pass it on to others. I wrapped mine in plastic wrap, but is there a better way to store it?

  15. This is great!! I Just made this for my niece and nephew while baby-sitting them and they are LOVING it! Thanks for sharing the recipe. When I was in 6th grade my teacher presented us with this for a science project and I always loved it!

  16. I made this with my 2 year old this morning and it was a big hit. I had to nurse my daughter so I set him in his high chair with a few cookie cutters and let him have at it. Unfortunate I got distracted with my daughter who had a diaper disaster and when I came back the gak had gotten onto his shirt, the fabric cover on the high chair, the chair cushion and the floor. I had no problem removing it from hard surfaces but I think the cushion is ruined (it was old anyway) and I’m concerned about washing the shirt and fabric cover on the high chair. Anyone else have this experience??? We used blue dye, which stained our hands ๐Ÿ™

  17. I just made this for my kids, they’re having a blast!!! Instead of food coloring I used an envelope of Kool-aid, not only the color came out bright but it smells amazing too!!! It hasn’t stained their hands or anything so far, I’ll report back if it does.
    Thanks for sharing this awesome recipe!!!!!!!!

  18. Thank you so much for sharing! This was one of my favorite things as a kid and would love to introduce it to MY kids!!! I am going to attempt to make this tomorrow lol thanks again for sharing and lovin your site!!!

  19. Thanks for the recipe. My family just made it and it couldn’t have been easier. I recently found your blog and I am hooked already! Thanks again!

  20. We made this with green and it worked out fine, no sticky pieces. We took it to a play date and left it to share the gift ๐Ÿ™‚ but we made orange today & I have sticky bits everywhere… More borax? Less? More water? No orange? Help! We want to make this work my kiddo loves it!

  21. We made this a couple days ago, and it was so fun! They quickly figured out how to push it down into a slightly tapered cup to make some really fun noises, too! Fun with flatulence!!! lol!

    1. Hey Caddie, II’m South African and made some today – you can get Borax at PnP in a small white and tan container- Robertsons brand – usually in the same place as the washing powders, although I’m sure hardware shops would be able to help you as well… And I’m assuming school glue is the same as wood glue – although ours has a bit of a chemical smell – but I made a huge batch so that might be why!

        1. Hey Alain,
          I did try it – the chemical smell didn’t go away and the ingredient amounts were way off – I think wood glue is too strong! I’m thinking of trying that Pritt craft glue – it’s also in a little bottle. I haven’t gotten around to it yet – maybe give it a go and let us know?
          There’s a shop in the city where I work called Hall’s Adhesives – I’m thinking of popping in there to see what they have too…

    1. I’m pretty sure it won’t work without borax. There may be other recipes on the web that don’t include it, but I know for sure this one needs it. :/

  22. Hi, I just made this for my 2 year old yesterday and he LOVED it. I’m just wondering how long this is supposed to last. When we finished playing with it I put it in a ziplock bag. When he woke up from his nap he wanted to play with it again so I got it and noticed a large amount of water had seeped out of it. I poured off the excess and we played with it for quite a while. Now the next day about half of it has turned to water. We are playing with the remaining half but I’m wondering is it supposed to last longer?

    1. When I read this I thought it was such a great idea for my 2 year old! but when I tried to make it it turned out very rubbery and hard, I am unable to stretch it like it should be. I was wondering in the recipe it says to add water to the glue bottles and swoosh them and pour out.. So how much water do I pour into the bottles? Maybe that makes a difference?

      1. Helen I believe the recipe says to fill the glue bottles with water, swish around and empty that water into the bowl mix with the glue already in it. That’s what I did and it worked out well.

  23. Are you supposed to have a bunch of excess water in the bowl? I followed all the directions like I was supposed to and I have a glob of stuff swimming in a bunch of water.

  24. This is wonderful. I remember this from many years ago, but we just called it slimmed…….I love smearing my brother with it……I am ordering this for my grandson, but will have to use some for Uncle Bub…….

  25. Did anyone have any issues with the “gak” staining hands after playing? I’m thinking I may have added a little to much dye.

  26. I decided I didn’t have enough stocking stuffers but I had reached my holiday budget. So I was stoked when I found this recipe! I made it and it turned out fab!!!! I had such a blast making it that I ened up making 8 batches. I have 5 kids so I’ll have back up for the rest of xmas break. But I’d just like to thank you! This is a great idea. And with store bought gak costing $7 for .4 lbs it’s an awesome way to save money since it only cost about $2.50 a pound to make at home. Thank you soooo much! It’ll help the kids stay busy and me sane without going into debt!

    1. Yay!! SO glad you made this and that it turned out. It really is such a fun and easy gift that the kids will LOVE. I hope it helps provide hours of entertainment over break. Merry Christmas!!

  27. Tried to make this but it turned out like a rubber ball. It wont stretch it breaks in to pieces when pulled. What did I do wrong? I did the instructions just as you said to do.. Help? ๐Ÿ™

    1. Did you use Elmer’s glue? And what kind of food coloring did you use? I haven’t had any problem before but wondering if the food coloring or brand of glue could make the difference. :/

      1. Yes I used Elmer’s white glue and Betty Crocker food coloring, but it was the gel coloring. It mixed up good but suddenly it started getting very hard so I used my hands to finish mixing it, but during the mixing mine didn’t look like it the picture you posted. Your picture looks kind of smooth but mine will so hard it was sticking to the spoon. Also, there is a bunch of water left in the bowl, is that normal?

  28. Seems that the trick to the right consistency is the amount of Borax used. Use too much and the “Gak” is harder and not stretchy. Use too little and the Gak is sticky and messy. So the key is the Borax. If it is too sticky, add a little more Borax (dissolved in water). Too “crumbly” adding a little more water and mixing will help; but just try not to add too much Borax next time. Hope that helps!

  29. I don’t know what I did wrong but it’s rock solid and our hands are green . Ended up throwing it out. What a disappointment ๐Ÿ™

  30. I tried making it with my class and it didn’t work ๐Ÿ™ We just ended up with stretchy glue in a lot of water. I am thinking because the kids used water from the bathroom and it wasn’t warm. Do you think that is why it didn’t mix well?

  31. Dear Liluna,
    I red your fantastic idea of making slimy with kids at home. By searching for opportunities to by the Borax, I’ve found an interesting statement in the german website of Borax:
    “Wichtiger Hinweis
    Borax darf nach neuen wissenschaftlichen Erkenntnissen nicht mehr an private Haushalte verkauft werden. Borax steht im Verdacht Schรคden am ungeborenen Kind zu verursachen.”
    Translation: do not use this product any longer!
    Love to read more of your great ideas!

  32. I just did this with my 4 year old and it came out perfectly. And he is still playing with it, and I’m sure will be playing with for awhile. Thanks for the great idea!

  33. My friend sent me to your recipe and I just made this with my 3 year old today. WOW!! He is loving it and I love how easy and cheap it was too. Thanks so much for an awesome project!

    1. You’re welcome. It has become a regular thing in our house to make GAK because it’s so easy, cheap and the kids LOVE it!! So glad yours loved it too! ๐Ÿ˜€

  34. DO NOT use Kool Aid! My first batch turn out to look like runny, scrambled eggs using Kool Aid. But my second batch is fantastic and I followed these directions exactly, just skipped the coloring, The kids (two 7 yr old boys) could care less that it is white and are happily playing now! Thx

  35. I pinned this awhile ago and finally got all the ingredients to make this. Just made this with my kiddos. They had a blast making it and now playing with it. Already begging me for more colors. It turned out great for us, not sure why some people are having trouble. I used white rose art glue and regular green food coloring, no staining of any kind for us. It was really messy/watery as first and I wasn’t sure it would firm up, but just as you said, after a few minutes it turned into “the perfect GOOEY consistency!”

  36. I know this is a late comment, but I’ve made 5 batches of the stuff already. I found that Elmer’s school glue works perfectly. Elmer’s multipurpose glue will give it the hard consistency people are complaining about, no matter the borax to glue ratio. I’ve even tried the liquid starch in lieu of borax as well and can’t get it thick enough and is a bit too “gooey” where it sticks too much to hands even when the proportions are changed. Hope this helps. When using Elmer’s Multipurpose glue, I eventually found an acceptable texture (still firm and doesn’t flow well, but malleable) at about half the borax+water quantities as recommended to 8 oz glue.

  37. I tried this twice and it didn’t work! Same result both times — too much water and it wouldn’t congeal. It was like the consistency of cheese curds! Bummer! Any tips? I used Rose Art glue, is that the problem?

    1. I just made this with my 3 little loves! They are having a blast! I am noticing a few little bits get broken off put we have just been squishing it all back together. The boys (9 & 6) found that if you squish it into cups, it makes some interesting noises! My daughter (2) is making snakes!
      Such a great fun idea!! Thanks! P.S. what do you store it in?

      1. SO glad they like it!! I like to store mine in a tupperware. I also have found cute containers in the dollar section at Target that are Disney and other character tupperwares that work perfectly. ๐Ÿ™‚

  38. I found your idea on pinterest. My 4 year old son and I just finished making it and he was amazed! He said it was magic! Thanks so much for brightening our rainy day in Georgia!

    1. Thanks for the sweet comment, Amanda! So glad your son loved it and thought it was magic. It is definitely one of our favorite activities! Have a great day. ๐Ÿ™‚

  39. Love this! We just made it and its a big hit. My first batch I didn’t follow the directions perfectly. (I added too much borax) It was pretty stiff the second time I followed the right amounts of everything and it turned out great! Also I used cake mate neon food coloring and put in the whole bottle it was not bright at all so next time I will use betty crocker food coloring. Kids are happily playing along with my hubby ๐Ÿ™‚ Thanks for posting!

  40. Hi! I am a 1st grade teacher and am wanting to make this in my classroom. I have 23 students. How many batches do you think I would need to make? One of these batches be enough for how many kids?

  41. I don’t know anything about Gak but would love to make some!
    Can anyone tell me:
    1) How to store it
    2) How long it will keep
    3) What happens when it falls on the carpet or clothes

    Appreciate any help on this. Thanks so much!!

  42. We found this, and just made it as a science demonstration with my kindergartener! How fun. And she really could do it all herself! Thanks for posting!

  43. We made it for the first time and absolutely love it!!! But I had a question…if it’s turning our hands pink does that mean we added too much food coloring?? Or will this fade after she plays with it for a while?

  44. Love this idea! As a kid, Gak was a favorite in my house. I think I remember making it at home once too. Thanks for sharing. Pinning!

  47. I have attempted to make this 4 times and every time I have excess water and it’s just a lump of goo. It won’t stretch, it just breaks apart….. any suggestions as to what I’m doing wrong?

  48. Thank you for the step by step instructions. I am glad that you mentioned the part regarding the “getting stringy” because otherwise we would have thought that we made a mistake. It turned out awesome!

  49. Thank you! My kids just made this (pink and yellow) and it’s such a blast! So easy too! We are in Arizona too so we are stuck inside and this is making the day fun (getting the cookie cutters out now).

    1. SO glad you guys made it and are having fun, Jona! Definitely beats the heat to be inside and playing with Gak when it’s 100+ outside. ๐Ÿ™‚

  50. We had fun with the recipe but next time I will pull their hair back in ponytails and remove their clothing! I’ve spent the last hour scrubbing the gak off the clothing with a bristle brush and giving bathes. Someone asked about the different coloring…we did the neon also and the coloring mixed with the glue as directed. We all ended up with colored hands. We used the bristle brush to scrub as much off as possible. If it gets on clothes then use hot water and a hard bristle brush…then soak your clothes with a stain remover to be on the safe side. I just didn’t think of these things in advance. I guess looking like colored little aliens was part of our package! LOL!

    1. Thanks for the tips, Mae! It can definitely get messy that’s for sure – especially if it’s their first time making it. And sorry your hands were dyed… not sure why it doesn’t happen for us. :/

  51. I made this today with my daughter. First batched was awful. I followed the recipe exactly and it came out hard and the consistency of a rubber ball and had zero stretch to it, just crumbled.
    The second batch I made I added the borax a teaspoon at a time until I got the consistency I wanted. I ended up using only half of the borax/water mixture. I think next time I will use even less.
    Great activity but a bit finicky to get it just right.

    1. Sorry you had so much trouble, Megan. I’ve made this recipe countless times and have never had any issues. Not sure what may have caused it to be the consistency of a rubber ball. :/

  52. I tried it for the first time with my 6 & 8yr old daughters and absolutely loved the result. Followed the recipe exactly and made teal & orange color. The girls were super thrilled with their gak. Thanks for the recipe !!

  53. I’m planning on doing this for my son’s Teenage Mutant Ninja Turtle party and wondered about what the yield is of one recipe. Is there enough for 8 little kids to take a fun amount home or should I double?

  54. Thank You! This is the best craft! My 2 year old daughter and 4 year old niece are enjoying gak as I type. I was just wondering what is the best way to store it? And how long does it last?

  55. I just made this with Elmer’s glitter glue and it worked great! I added food coloring and it turned out a dark purple glitter glob! What fun!

  56. My 3 year old daughter and I made this today. Amazing fun! My husband and I were totally playing with it too. It was a great one on one time with her as well which has become a little difficult with a nee baby in the house.
    We used the McCormick egg dye color chart to make teal and it came out beautiful! No staining either ๐Ÿ™‚ I did however warm the water in the microwave for 25 seconds to ensure the borax would completely dissolve. We did have some excess water but the more you mix aand kneed its soon absorbed.
    Thank you for the recipe. I will certainly be hanging out here more especially now that I’ve read you are a fellow Arizonan!

  57. Is this recipe safe for children? I saw information that stated that Borax is not safe for children even in small amounts.

  58. Heya we’re with the key moment below. I found this kind of plank i to locate Advertised . handy & it helped me to out and about much. I am hoping to present a thing once again as well as guide people such as you taught me to be.

  59. I just made this today and I love it! I made it for my two year old son and three year old nephew. It’s super easy to make and only took like three minutes. I split the recipe because it was a lot and made both blue and green so the boys didn’t fight over it! Lol. Thanks for the recipe!! =]

    1. I’m so glad it was a hit, Amanda! We make it at least once a month, and the best part is it lasts for a long time if you store it in an air-tight container. ๐Ÿ˜‰

  60. This looks like so much fun! I can’t wait to try it with my 4 year old! ๐Ÿ™‚

    How long does it last? Would you just store it in a plastic sandwich baggie?

  61. Thank you for the wonderful idea. I made it exactly as you said and it turned out perfect. My 8 & 4 year olds love it and two days later are still playing with it. Is it OK if I share this on our website and link back to this page?

  62. I didn’t use Elmer’s glue which is why I needed a bit more Borax as it was too liquidy. Once I found the perfect consistency the kids did play for this for over an hour (and I added a ton of kitchen utensils), great fun!

  63. Good morning guys, nice tutorial! I’ve got a prblem and it is that I’m from another country and I don’t know what borax is, so, can anyone explain me what it is so I can try this awesome DIY?


  64. Love your site! Such a bright and happy page, with easy, fun ideas! From Manitoba, Canada, but found you from my FB page, and will keep in touch. My grandkids, Maya and Miles, will love the GAK! (Especially in our loooong winters!)Thank you!

    1. You’re so sweet! Thank you, Patricia!! I hope you can find loads of inspiration here. I know the grandkids will love the GAK – haven’t met a kid who doesn’t love it! ๐Ÿ˜‰

  65. Hi, I want to make this for a party favors for my daughters Frozen them birthday. Do you think I can do this Gak recipe in large quantaties? Were talking 20 + kids…
    ANY insight helpful! Thanks!

  66. Hi,

    I love your DIY Project, but here in Germany, Borax is not available, since it is classified as severe nerve poison, maybe you have a more kid friendly solution?

    Best wishes fro, Germany

  67. I have made the homemade gak two times and both times the slime seperated and looked like curdled egg. It also had lots of coloured water left in the bowl. Do you have any idea why?? Ta

  68. Hi there, this gak looks awesome but I have a question … can you store it in a ziplok bag or a playdoh container and if so how long does it last?

    Please let me know asap.

    1. Hi Sue! I’v enever tried keeping it in a ziploc bag but I think it would be good for a few days as well as in the playdoh container. We usually keep it in tupperware and it lasts a few weeks. ๐Ÿ˜‰

  69. We followed the instructions and our GAK did not form into one big gelatinous lump. There was a lot of excess water and broke apart when squished. What did we do wrong?

  70. So im having an issue with mine. Its like soup with chunks ๐Ÿ™ ive been mixing with my hand for probably 30 min and its just breaking up the chunks but doesn’t seem to be mixing into the water

  71. When you say to fill the emptied glue bottles with warm water, shake, then add to the mixture ; do you mean fill them all the way as like a measurement and to get the extra glue out? Or just put a little water in them and shake for the extra glue to come out?

  72. Not sure what I did wrong but my “gak” wouldn’t come together as smoothly as you show in the photo – was squishy and interesting but not smooth!

  73. Very imaginative and practical. These kind of resources are very important for children because they allow them to play with their own hands and train their psychomotor and imagination without using expensive technological resources.

  74. how do you remove “Gak” home made or otherwise, off my new car seat, after it has dried? Please help my car is NEW, with cloth seats.

    1. Hi Carol! I’m so sorry this got on your car. I’d try spraying it and letting it set for awhile and then scrubbing with washcloth. Even though gak is super fun with the kids, it can be messy. ๐Ÿ™

  75. I am a little confused with how much water to use. Is the 1/2 of water the total water or 1/2 cup plus two bottles full of water? Mine had water left in the bowl and it was a little hard. I am hopping it will soften a bit over night.

    Love the idea, thanks.

    1. Hi Kathleen, you may have already found an answer to your question but if not, Spotlight, Officeworks and Big W have Elmers Glue. Found this out after ordering several bottles from USA in 2017.

  76. Hi!
    For step 2, you say to ‘fill the bottles with warm water and shake’ I’m assuming you’re referring to the glue bottles… Is this equivalent to adding warm water without using the empty glue bottles? I bought a large bottle of glue and don’t want to buy more little bottles if I still have glue. ๐Ÿ™

    Thank you so much!

  77. I was wondering how much one batch makes? Im making it as kids favors and have 4 ounce jars and Im not sure how much I would need to make. If you wouldnt mind getting back to me, that would be greatly appreciated! Thanks!

    1. Sorry to get back to you so late. Did you try making it? I haven’t divided the gak like that before, but you could easily fill quite a few 4 oz jars with it. If you tried that, I’d love to know how many you got out of it.

  78. Looks like a lot of fun! I have a 3 yr old. Quick question: is Borax safe to touch e.g. to lips, nose, eyes, etc? It does say “keep out of reach of children” on the box.

    1. It is tons of fun!! I wouldn’t recommend it getting on faces. Not sure what would happen, but it’s probably not the best. I usually measure that part:)

  79. I’m so glad I followed your instructions. I agreed to volunteer for the 8 year old boys class for our Police and Youth Day Camp on tomorrow. I was out of options and thought of this gak. Your instructions were great. Of course, I had to try it out first before I presented it to the eight year okds. I wish I could post a picture of the gak I just made. The kids are sure to love this tomorrow.

  80. Can I add the food coloring after? i was thinking i can just make a big batch of white gak then separate it between my boys and they can color their own, would that work?

    1. The coloring needs to be added when it is being mixed together. I don’t think it’d get mixed in real well, once it has formed into the gak. I haven’t ever tried, so I can’t be certain, but that’s what I would think. One batch is the perfect amount for one person, so usually I let them pick their color and I help each kid with their own. Let me know if you do try coloring it after. I’d love to know!

    1. I don’t think I’ve ever measured it or anything, but the ingredients make plenty for one person. I was able to fill about 8 4oz capsules, so I guess it makes close to 32 ounces. I usually make one batch/kid. If they’re smaller kids, you could split it, between 2 kids. It just depends on how much you want them to play with. Hope that helps!

  81. Approximately, how much does one batch make? If every kid gets to take home about 1/8 of a cup? Thanks in advance!

  82. Hi ladies,
    Can Gak be made without Borax? I want to make it, but cannot get Better Ras in my current location.
    Thanks for any suggestions.

    1. I honestly don’t know. I haven’t tried. Google suggests maybe cornstarch or liquid laundry starch. I don’t know what the outcome will be, but you could give it a try. Let me know how it turns out!! Good luck!

  83. Hi there,

    We don’t have Elmer’s glue in this country… Do you think I can substitute it with anything? Please let me know because the gak looks amazing.

    1. I don’t think so! I haven’t used another glue, but they all have same ingredients, right?? And, I think the regular food coloring will be fine! I honestly can’t remember if I’ve tried it! Hope it all turns out! Have fun!

  84. Mine didnt work. I did it just like the recipe. Even tried it 3 different times and it didn’t look anything like your picture. It was just a really big waste of glue and brought my mood down. Hope it works for everyone else maybe.

  85. Hi Lil’ i’m living in Italy. Could you tell me which kind of material is Borax? Elmer glue is a normal glue for school, isn’t is? Thakyou for share. I want to try this now!

    1. Borax is a powder material. People use it in many ways. You should be able to find it by cleaning supplies. And, yes, Elmer glue is the normal glue for school ๐Ÿ™‚ Hope that helps and hope you can find the borax. Thank you!!

  86. Wow you have a house full of love and fun. I had 8 kids in 9 years Including 2 sets of twins. I loved being a mom. I love your ideas. I now look for fun ideas for grandkids. I have 33 in all but I will only have 4 here for the next 2 weeks. We will be doing the gak for sure ????. And we are doing a treasure island day. Starting with the old movie and making treasures maps. If you would be interested in some fun ways I coped with 8 kids email anytime with questions or I can just list some ideas. Thanks for your fun blog. Debi

  87. I used to make play dough for my son but this is much easier since it doesn’t require cooking. Easier clean up too. Thank you for the detailed and lively instructions!

    1. Those children were allergic to borax. Unless your children have a borax allergy, they will be fine. ๐Ÿ™‚ Hope that this helps ๐Ÿ™‚

  88. Made this gak. Although my girls hands are blue and pink from the food coloring. How do I prevent this from happening again?

    1. Hmmm..I wish I knew. My kids get colorful hands when playing, but they can play for hours with it, so I never mind. It usually comes clean after washing.

  89. OH wow. Great idea! Now I know exactly what to do the next time I babysit my god-daughter. She’s a ball of energy full of curiosity so this should keep her distracted for a good while. Thanks for this!

  90. My 3 year old and I just made this. She LOVES it and it turned out perfectly.
    Can’t wait to try different colors.
    It’s already been 20 minutes of play with no signs of slowing down. This tired and pregnant momma thanks you!!

  91. Iโ€™m thinking about making this for a birthday party! Does this store well?? If I let them take some home in jars? Or is it a play one time with and throw away thing??

  92. Are you filling the two glue bottles completely with water? All the way to the top or just a little water to washout the remaining glue?

  93. if you take this on the road. when it gets hot does it melt and get all over the carpet? has anyone had that problem?
