Color Cubes

Ice cube tray
Food coloring
Tall baby food jar

Fill the ice cube tray with water. Add drops of red, yellow and blue to the compartments.

After the cubes are frozen, place a red cube and two yellow cubes in a glass. As the cubes melt, watch what happens.

Do the same for yellow and blue and red and blue. It is fun to watch the ice melt and change into another color.
