Product Details

Pour water into an “empty” glass and watch as it turns into purple grape juice. Continue pouring from glass to glass and you’ll serve up some lemonade, a fizzy soda, then milk and finally Pepto-Bismol®. Is it magic—or simply chemistry? This fascinating demonstration allows you to tell a creative story or just “get to the chemistry of it” with the acid–base and precipitation reactions occurring in the glasses. Teacher Demonstration Notes included.

Concepts: Acids and bases, solubility, precipitates.
Time Required: 20 minutes
