Call it slime, bizarre slime, gak, goop, oobleck, flubber -- no matter what you call it, kids love to make it. Recipes for stretchy non-Newtonian fluid abound, but many of them call for the addition of borax, a salt-based laundry additive. If you want to make bizarre slime but don't have any borax, you can substitute Epsom salt. When mixed with glue and water, Epsom salt causes a chemical reaction that creates a stretchy putty.
Things You'll Need
2 tsp. Epsom salt
4 tbsp. white glue
Pour 2 teaspoons of Epsom salt and 2 teaspoons of water in a cup.
Stir the Epsom salt and water mixture until the Epsom salt is mostly dissolved. It may not dissolve all the way.
Pour 4 tablespoons of white glue into a bowl. Squeeze 3 drops of food coloring into the glue.
Pour the water and salt mixture into the bowl with the glue.
Smash the glue and water mixture together with your fingers until it turns into slime.
Store the slime in a plastic sandwich bag to keep it fresh between playtimes.
