Did You Know?
- If you mix juice and baking soda in a cup, it foams and bubbles. The bubbles form because the chemical reaction releases carbon dioxide. It also creates water.
- During the American Revolutionary War, U.S. Army members wrote invisible messages using acidic liquids so enemies could not read them.
- Another fun experiment to try is to mix half a cup of grape juice with half a cup of water. Add 1 teaspoon of baking soda and stir it to create your own fizzy Valentine’s Day drink!
- Instead of grape juice, experiment with other liquids. You can try lemon juice, apple juice, vinegar, and milk because all are slightly acidic. Find the liquid you think works best!
