- 1 box of Baking soda

Measure ½ cup vinegar and pour into bowls. Add 10 drops of food coloring. Stir with spoon.
Repeat for desired amount of bowls. (for this activity we chose 3 bowls/colors)
Pour baking soda onto pan into an even layer. You can gently shake the sides of the pan sideways until it evens out. Or, use the bottom of a spoon to even it out if you’d like.
Fill dropper with desired color of vinegar. Slowly drop the colored vinegar onto the baking soda.
Watch what happens!
Continue this, alternating between colors. Fill up the tray with colors.
Experiment with dropping colors on top of other colors to see how they change.
