Dancing Pasta Watch pasta "come alive" in this cool experiment. What you need:
Step 1: Fill the drinking glass with water. Step 2: Mix in a teaspoon of baking soda. Step 3: Add a teaspoon of vinegar. Step 4: Add the spaghetti pieces. Step 5: Watch as your spaghetti seems to come alive! The science behind it: Baking soda (a chemical also called sodium bicarbonate) reacts with vinegar (also called acetic acid) to form carbon dioxide gas. This gas rises to the water's surface as tiny bubbles. The rising gas bubbles bump into the sinking spaghetti pieces. The bubbles lift up the pasta, making it rise to the surface. Once the bubbles slip away at the surface the pasta sinks again, until it encounters more bubbles. This makes the pasta appear to dance!
