Instructions
Mix a good amount of baking soda with water; add different colors of food coloring to make the colors in a rainbow. Freeze for a few hours or overnight. Let the cubes defrost a little and place colored soda cubes in a deep plastic container. Invite your child to drop small amounts of vinegar onto the soda cubes. Observe as the cubes fizz!
Warning – Careful supervision is required so vinegar doesn’t get into the eyes of little ones.
