Crayola Bath Dropz Color, 60 Tablets, 3.59 OZ

Crayola makes bath tablets that make the bath water different colors, mine really enjoy being able to pick the color and toss it into the bath.

Crayola makes Bath Dropz that don't stain skin or the bath and would be perfect for something like this. You get 60 tablets for like $4 and you can mix them to make different colors, we use 1 or 2 tablets in the bath and it colors the entire tub of water.
