Dancing Apple Seeds: We placed apple seeds in a glass full of Sprite. Apple seeds are more dense than Sprite so they originally sank to the bottom until air bubbles started to form around the seeds, which then forced the seeds to float up to the top. When the bubbles popped the seeds sank back down. This made the apple seeds look like they were dancing!
Ozzing Pumpkin: We mixed hydrogen peroxide, dish soap, food coloring, dry yeast and warm water together to get a reaction. The dry yeast sped up the decomposition of the hydrogen peroxide by releasing the oxygen molecules into the dish soap making the pumpkin oz foam.
