How to make Gak (Slime)

    Posted by  ·  July 24, 2009

    We had a few days of rain around here so we made some slime to occupy our time inside. Just two ingredients and you will be able to really impress your kids!

    gak1

    To make simply mix equal parts of liquid starch and glue together.

    We placed 1/4 cup liquid starch into a sandwich bag and added about 3 drops of green food coloring.

    gak2

    Next add in 1/4 cup glue

    gak3

    Mix well. It will start to form a solid blob. There might be a  bit of liquid that will not mix in, just remove the blob of slime and discard the bag with the extra liquid.

    Take it out of the bag and have fun!

    Looking for more ways to impress your kids? Try making oobleck!

    Need a way to use up the rest of the starch? Try making some marbleized paper.

    You will find other rainy day activities here.

      I used a bit of water and less Starch. Turned out great! Using this as cave slime craft for our VBS. Going to try Glow in the dark slime!

      thigh attached to each other, breasts, wings and backbone.Prepare the stock: In a large pot over medium heat, warm 1/2 cup of the olive oil. Sauté the wings and backbone until slightly browned on all sides. Deglaze with 3/4 cup of the wine, and add 8 cups of the water. Simmer for 1 hour over medium heat to make a light broth. Strain and set aside. Prepare the capon: Season the rest of the capon pieces with salt and pepper. In a large skillet with high sides, heat 1/2 cup of the oil and add the capon. Sauté gently on all sides until pale golden. Remove the capon, and reserve on a platter. Add the vegetables to the pan, and sauté just until warmed through. Deglaze with the remaining wine, and put the capon pieces back into the pan on top of the vegetables. Add enough of the capon broth to cover. (If there isn't enough stock, add the remaining water until you have enough liquid.) Bring to a simmer, cover, and cook until the meat falls off the bone, about 35 to 40 minutes. Carefully lift out the capon pieces and the vegetables, and store them in separate bowls. Raise the heat under the skillet, and reduce the cooking liquid by half.Meanwhile, remove the capon meat from the bones. When the liquid has reduced, place the meat back into the broth. Stir in the remaining 1/2 cup olive oil, and adjust the seasoning. Serve a scoop of the vegetables topped with the capon meat and broth. Shave some white truffle over the top of each serving.

      Super disappointed in this!! The glue didn't take on the color. And it was really wet still- not like the slime I remember as a kid!!

      Would it work with home-made liquid starch (corn starch and water mixture)?

      Add borax to the mix. The ratio is 2 parts glue, 1 part starch, and 1 part borax. The more borax the harder it becomes.

      I made this today for my boys ages 3 & 4 they loved it but it is still too sticky even after playing with it for a while. Is there anyway to speed up the process of making it less sticky?

      We made this tonight and I thought it wasn't working either. It was VERY "WET" when we took it out of the bag and it stuck to our hands a lot. But the more we played with it the better it got! Very messy but my boys (ages 5 & 8) LOVED it!!

      I'm surprised! We made this tonight and we're
      Very disappointed as it didn't come out. We used
      1/3 cup Elmer's glue and 3 drops of red food coloring
      And then added 1/3 cup of liquid starch. It never
      Formed a ball. We kept mixing and mixing in the
      Baggie. Sigh. I'm sure I missed something.

      I use to do this in the Art Room when I was in High School all the time. Just throw a little acrylic paint in there instead of food coloring, it all works the same.

      Does clag school glue work or does it have to be more of a wood glue consistency?

      I found this recipe because I was looking for a GAK recipe without using Borax. Borax is a poison and I am not comfortable with my children handling it. I looked up the ingredients of this brand of liquid starch and it contains Borax. I wanted to let other moms know in case they were interested. You can make home-made liquid starch with corn starch.

      I just made this with three children - we used fine glitter instead of food coloring and at first I thought it was horrible - it was very stringy and didn't stick together at all, plus it was super... "juicy" I guess is the word. But I kept kneading it for brief periods and washing my hands in between, letting it sit for a little while, and after a while the consistency was excellent. I think the trick is to get the extra liquid off and then it's good. Just for comparison's sake I live almost at sea level in a dry climate and I used Sta Flo brand liquid starch and Elmer's glue. It turns out a four ounce bottle yields just over a third of a cup (it should be half a cup because 4 oz is 1/2 c, but I guess it sticks to the inside and you don't get that much out unless you're REALLY patient). So if everyone has their own 4 oz bottle of glue you can just measure out the starch and then have everyone squeeze their glue into the bag. You could use the bag in a cup trick to hold it upright so it doesn't spill.
      Also - if you have extra liquid just add more glue to it and you'll get more gack! It worked for me.

      My 8 year old has to do a "How to" demonstration in front of the class. He is going to have the entire class join in on the fun and make it at the same time. We tested several methods and this one was best for the whole group demonstration- all you need is Sta Flo, Elmer's Glue, food color and a baggie (or two). Don't forget to mix and mix and mix! We then needed to drain the left over water/ingredients and place in another clean bag. He can't wait to share it at school!

      I just made this, with the exact formula (Elmer's, and sta-flo) and it didnt turn our right. I bought real gak from target last week, and decided to make some on my own.i feel like its missing another ingredient. It smells like gak, but it's harder and less like slime than the real stuff. Don't get me wrong it's still fun to make, but don't expect it to be exactly like the original

      This mixture didn't work for me at all. I almost doubled the amount of glue and it still was just liquid. I live in the mountains with high humidity and wonder if that could affect the result. I'm not giving up though and will try a few more mixtures.
    37. Wednesday, June 9th, 2010
      Anyone know how to make your own liquid starch?

      CORRECTION to previous comment-- I figured it out! After combining the mixture for about 15 minutes (OK so my little one did this) I walked away to check and see if I had left out a step and to my surprise when we got back it was slime!!! YEAH!!!

      I'm curious, there are only posts of people who have not tried the recipe yet, but are super excited to try it. I need a review of someone who has tried it and loved it as well...I'm going to try it tomorrow, but I have two different recipes...one that uses the starch, and one that uses borax. Do you know which turns out better? or the difference?

      We made slime today for my son's 5th birthday.It was themed "Ben 10", so we called it Alien slime and put a big goggle eye in it and let them put it in green plastic easter eggs to keep. I found that it had alot of left over liquid. I was afraid we had done it wrong, but it was all good once we drained the fluid away. the kids loved this activity we dyed it neon green.

      I have been searching for this recipe for years! I made it 15 years ago when I was in Advance Child Development and the recipe got lost after school was out. I kept looking for it and never found it. Thanks so much for posting!

      I couldn't find any liquid starch today except in a spray bottle (one store had non-aerosol). Does that work? If not, where do you usually find it?
      • Friday, July 24th, 2009
        I bought the liquid starch at Wal-Mart and I have also found it at Dillons (King Sooper). It is with the laundry supplies.

      We LOVE this stuff! My hubby will spend hours squishing this stuff while he watches TV. The first time we made it, my 2 yr old played with it all afternoon and it was the longest she had ever played with anything other than her dolls!
    53. Friday, July 24th, 2009
      Ewww!! My son isn't old enough for this yet, but I might make some for myself. :)

    56. Friday, July 24th, 2009
      I have a recipe on my site for clean slime, it's VERY similar but uses cornstarch just like oobleck. I love giving this stuff as gifts....I think it makes other moms mad, the ones that don't like there kids playing with cool stuff. You know what i"m talking about!
    57. Friday, July 24th, 2009
      You read my mind, I have been looking for a reliable gak recipe all week and wasn't sure the ones I found would work. Thanks! And this is the first time I have posted on your blog so I also want to tell you I really appreciate all the other ideas you share.

      if "There was a bit of liquid that would not mix in." what did you do with it?

        Just throw any extra liquid away.
