• Film canisters (Fuji film brand; many photo labs will give empty canisters away for free)
• Baking soda (sodium bicarbonate)
• Vinegar (acetic acid)
Note: Do this project outside. The baking soda and vinegar reaction makes a mess! Plus your rocket is going to fly high! As soon as you put the lid on the film canister, move out of the way—it can blow fast!

2. Pour about two teaspoons of vinegar into the film canister.
3. Gently put the lid on the film canister and snap closed.
4. Turn the canister upside-down, put it on the ground, and stand back.
5. After a few seconds, the canister will shoot up into the air. If your rocket always fizzles, try a film canister with a tighter-fitting lid.
