Making fizzy candies with kids can be an educational activity. The bubbling sensations and the coolness of these treats are given by the carbon dioxide that results from mixing baking soda (sodium bicarbonate) and citric- acid water in your mouth. Keep the candies in a sealed plastic bag or lidded jar to avoid humidity. Food coloring is optional—but it helps make these a treat for the eyes as well!

Directions

1. In a mixing bowl, combine powdered sugar, cornstarch, baking soda, and citric acid. Mix well.
