Pour 2/3 of a glass of orange juice. Add 1 tsp of baking soda. Orange juice will bubble and fizz right before your eyes! Try this experiment out on other juices. The acid in OJ creates a citrus reaction with baking soda, releasing CO2. Apparently this mixture is good for your skin too. ;) I tasted it and it had a very unique flavor, not as good as sugary Sunkist! Visit Sunkist for more orange experiments!
