Materials

• baking soda
• vinegar
• cup
• food coloring (optional)

1. Put a spoonful of baking soda in a cup. 2. Add a drop of food coloring if you have it (makes it more fun). 3. Let your little one pour in a splash of vinegar. 4. "WHOA!" Watch it fizz up. Ask: "What happened?!" 5. Explain simply: "When these two things mix, they make a gas — bubbles of air that go crazy trying to escape."
