How to Make Bizarre Slime Without Borax

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.
