It’s holiday card season, and that means…film canisters!
When you’re picking up your photos, ask to dig through your camera or photo store’s film canister recycling bin. Pick out clear film canisters with lids that pop IN tightly, and you’ll be ready for some rocketing good times.
Make some film canister rockets to shoot off next spring, or brave the cold to shoot them off now. Do you think the chemical reaction that makes CO2 gas to power your rocket will take longer in the winter? Why?
Here are directions for how to make them. They’d be great holiday gifts for kids to make for siblings!
