This is a fun project for children and it will make them WANT to stay in the bathtub longer!

What you will need: 1 cup grated Ivory Soap ®, 1/4 cup warm water, food coloring, plastic cookie cutters

1. Mix water, soap and food coloring together in a medium bowl. Stir the crayon mixture until it begins to stiffen.
2. Remove the mixture from the bowl and knead until it is the consistency of a very thick dough
3. Spoon crayon mixture into plastic cookie cutters.
4. Place the plastic cookie cutters in the freezer for 10 minutes.
5. Pop the crayons out of the cookie cutters and allow them to dry overnight or until hard.

You could also use an ice cube tray instead of cookie cutters as a mold for your Tubtime Crayons. These can be used as bath soap! Super fun! With these crayons you can color on the side of the bathtub or on tile walls and floors.  Children LOVE these!  I got this recipe from a cool book called
