Rocket Film Canisters, Set Of 12

Product Details

These canisters are perfect for building your Alka-Seltzer rockets! The tight fitting lid allows the pressure to increase enough for the rocket to fly several feet into the air. Great activity for changing the variables; amount of tablet, amount of water, with or without a nose cone, with or without fins, the way the paper rocket is rolled, etc. Online lessons include complete instructions for building film canister rockets. Also great for geocaching!
