To make slime at home, mix 1 cup warm water with 1/2 tsp borax in a bowl until dissolved. In a second larger bowl, stir together 1/2 cup Elmer's glue (clear or white) with 1/2 cup shaving cream. Pour in a splash of borax mixture into the glue mixture. Add food coloring or glitter if desired.

Stir with a spoon until the mass starts to form, then grab and knead it with your hands until it becomes firm and smooth, adding more borax mixture as necessary. We usually use about a quarter cup of the mixture, but just add a little bit at a time until the slime holds together and is stretchy.

Note, you can substitute water for shaving cream if you don't have any, but will need to use a full tsp of borax for the solution, and your slime won’t be as stretchy.
