Make a "Bottle Rocket"
Ever wonder how Fourth of July fireworks work? It’s all chemistry! A chemical reaction launches fireworks into the sky, and their colors are created when chemical elements and compounds are heated and emit different colors of light. Oooh and aaah over this fireworks-related activity—no fire needed! Just combine baking soda and vinegar in a plastic bottle, cork it, and start the countdown to fun!
Try it!
