Homemade Bathtub Crayons

In a small bowl, mix the soap with warm water and a few drops of the food color of your choice. Stir until mixture begins to stiffen.

Knead mixture until it is the consistency of a very thick dough. Spoon the mixture into cookie cutters, ice cube trays or paper cup molds, pressing down until no air bubbles remain.

Allow soap crayons to set in molds until firm. Pop soap crayons out of molds and let dry overnight until hard.
