The kids in the class have been overjoyed for our most recent sensory experience…Gak. Some people have different names for this fun part liquid/part solid/part slime/part liquid/part moldable stuff, but I call it Gak!
I made two different batches of Gak with my groups. One group got to make orange gak and the other group made a batch of purple Gak. They loved mixing up this slimly solution and watching the glue change right before our eyes! This is a fun process from start to finish.
To make Gak you need three ingredients:
These are the directions I use for my Gak:
The measurements do not have to be exact but it’s a good idea to start with the proportions below for the first batch. Just change the amounts of each ingredient to get a new and interesting batch of goo.
This recipe is based on using a brand new 8 oz bottle of Elmer’s Glue. Empty the entire bottle of glue into a mixing bowl. Fill the empty bottle with warm water and shake (okay, put the lid on first and then shake). Pour the glue-water mixture into the mixing bowl and use the spoon to mix well.
Go ahead… add a drop or two of food coloring.
Measure 1/2 cup of warm water into the plastic cup and add a teaspoon of Borax powder to the water. Stir the solution – don’t worry if all of the powder dissolves. This Borax solution is the secret linking agent that causes the Elmer’s Glue molecules to turn into slime.
While stirring the glue in the mixing bowl, slowly add a little of the Borax solution.
Immediately you’ll feel the long strands of glue and water starting to connect. It’s time to abandon the spoon and use your hands to do the serious mixing. Keep adding the Borax solution to the glue mixture (don’t stop mixing) until you get a perfect batch of Gak.
I like mine with a bit more “glue” and a little less “slime” so I usually end up adding a bit of glue at the end of the recipe. You can decide how you like your Gak!
It stores wonderfully in a Ziploc bag.
It will stick to your carpet or sometimes clothing, so be careful where you play with your Gak…kitchen is probably the best place.
Pick fun plastic objects to put in your Gak, they will pop right back out when you are done with your play time:
plastic animals or people (Duplo or Play Mobil brand)
utensils, spoons, forks, etc.
plastic cups or scoops
Here are some pictures of us playing with it at Crozet PlaySchool….
Ellie was showing us how the Gak stretches!!!
L was making imprints in the Gak. You can see the outlines of the spiders underneath her snake. Gak will hold a shape or an imprint for a few minutes before it starts to disappear. Such a fun texture to watch!
L is pounding out his Gak while D is making some imprints.
D told me that he made a Gak monster, isn’t it great?!
