    Another fun idea is to grow a PET TickleMe Plant and watch how the leaves fold and the branches fall down when you Tickle It!!

    These are poor instructions. Making ours based on these did not make the correct final product. The glue and water should be well combined before adding the borax/water.

    • Jessica

      We used these instructions and ours turned out perfectly! It says “mix” which means to combine to form one substance or mass. Thank you to the author for helping us find a fun activity on a snowy day!

    What is the borax for?

    • Eric

      The borax provides the reaction with the glue to make linked polymer chains (aka slime). For example, let’s say the glue is a bucket of chains and a handful of magnets is the borax powder. If you were to pour the chains out of the bucket, it would resemble glue pouring out of a bottle. However, when you add the magnets (borax) to the bucket of chains what will happen?? When you go to pour it out, instead of a stream of chains pouring out, you’d get a clump of chains. I hope that made sense, haha

    do I have to use borax

    • Eric

      You do. Borax contains a naturally occurring material: sodium tetraborate. This mineral interacts with the glue to turn it into a solid. You can experiment with other types of powdered laundry detergents to see if the results come out different.

    • Layley

      You can use other recipes such as Tide and glue (and shaving cream if you want fluffy slime) to make slime. You can use glue and eye contact solution too. There are many recipes out there, not just Borax.

      • Dasvon

        …..but keep in mind that Tide contains both borax and citric acid.

    • Ishana

      You can use salt too.

    how much borax?

  • ofamily

    This is fun to make and fun to use! The amounts of the ingredients we used are 1/2 cup of glue,6 tablespoons of cold water, 1/4 cup of hot water(not boiling hot),and 1/2 teaspoon of Borax. You mix the glue and COLD water in one bowl and the borax and HOT water in a different bowl.You can put any color food dye into the glue mixture.Then you add the two mixtures together and TA-DA! You have a fun, new way to make the same thing as Gak but maybe a little easier!

    Borax is not toxic… it comes from Boron which is an element on the periodic table. It is completely harmless and is often used as a detergent for washing babies clothing because of it’s purity. As with any substance not meant as a food product, care should be taken to ensure children do not consume it, but accidental hand to eye, or hand to mouth contact with Borax is not toxic. Luckily it tastes terrible so if a child accidentally tastes it they will stop immediately and want their mouth washed.

  • Prrrr

    We followed the instructions precisely and ended up with a very watery end product. Result was about one cup of water and one teaspoon of actual gak. I’ve made this using other recipes in the past and it turned out great; expected better from pbskids!!

    Hi – I thought I’d add to the discussion. I have 2 kids who both tried this recipe. My son’s worked great and my daughter’s ended up with tons of water. We tried my daughter’s again and found that timing is everything. My son and my daughter’s second try they continuously stirred everything. My daughter’s first try she paused a few times before stirring (waiting for the spoon, etc). You must continuously stir at the beginning to make it work properly.

    I’ve done this same recipe to make slim myself but a friend shared with me a disturbing video of a little girl with 2nd and 3rd degree burns from this please be careful.
