School’s back in session and we hope everyone is back into their routine and moving forward with learning! Speaking of movement, here’s a fun way to explore chemical reactions and pressure by making your very own rocket. Warning – this really does work, so be sure to partner with an adult and wear your safety goggles!
Items Needed:
Steps:
Vroom! What Happened?
Antacid tablets contain citric acid, and sodium bicarbonate, AKA baking soda. When this is added to water, a chemical reaction takes place and causes the tablet to fizz and produce carbon dioxide gas. When the lid is placed on the canister, the gas builds up inside of the container. The cap blasts off when the gas takes the path of least resistance and forces the lid off. When upside down, this shoots the canister into the air.
Expand on the experiment by trying different amounts of water, fewer antacid tablets, or try putting paper fins on the canister to see if you can direct the launch. Be safe and have fun!
