Yesterday, we made GAK at Crafternoon. It was such a hit! GAK is a polymer made from glue, water and Borax. It’s gooey, slimey, bouncy, stretchy, and not very messy at all. Here’s our video showing how to make it. NB: There is one small error in the video — instead of two teaspoons of Borax to 1/2 cup of water, the correct ratio is 1 teaspoon Borax to 1/2 cup water.
For detailed written instructions, and a lot of info on the science behind GAK, just visit Steve Spangler Science. (Steve recommends stirring the GAK. We shook it in little plastic food storage cups with tight-fitting lids. Either way is fun.)
