Materials
Various colors of transparent tiddlywinks
2-gallon Zip-Loc bag
Water
Directions
Place colorful tiddlywinks in a 2-gallon Zip-Loc baggie. Add a small amount of water (1/4 – 1/3 cup of water). Zip the bag closed and lay it on a light table or table surface. Invite your child to explore the baggie using his fingers – moving the tiddlywinks around. What happens when two colors land on top of each other? How does the color change?
