For the slime, you’re going to make 2 solutions. Do not, whatever you do, think it’s okay to just pour everything into one bowl. It won’t work, and your kids will miss out on the super-cool reaction!
Solution A: 3/4 cup warm water, 1 cup Elmers glue, food coloring. Mix until dissolved.
Solution B: 2 tsp Borax, 2/3 cup warm water. Mix until dissolved.
Pour solution A into solution B. Grab the glop and knead into shape (do not mix!). There will be a little extra water in the bowl, no biggie.
