In a small bowl, make the slime activator by mixing 1 cup hot water with 1 tsp. Borax laundry booster; stirring until fully dissolved. Set aside.
In a large bowl or container, add Elmer’s glue, shaving cream, foaming hand soap, and liquid hand soap. Mix well.
Once the glue mixture is stirred well, add 2-8 drops of food coloring (optional) to make the slime whatever color you’d like. Kaitlynn has made all sorts of fun colors.
Once the color is fully incorporated, add the Slime Activator ONE tsp at a time, stirring continually, until the slime forms into a ball (it only takes a few seconds).
Once your slime has formed into a shaggy ball, take it out of the bowl and start kneading it on the table (just like bread dough).
