Activity Overview
Fill your kitchen with oohs and aahs and all of the excitement of childhood with this fun and energizing vinegar and baking soda science experiment. Children of all ages will enjoy creating fizzing displays of color which seem almost like pretty fireworks on the tray, without the booms and explosions of course.
In this experiment, the baking soda is spread out on a tray and there are teacups of different colored food coloring. Children can dip their droppers into the colored vinegar solutions and squeeze the dropperfuls of liquid in spots on the tray.
