Film Canister Rocket
Have you ever wanted to create your own rocket? You can and it's easy!

Ingredients
Film Canister with Snap-On Lid
Water
Alka-Seltzer Tablet
Safety Goggles

Instructions
STEP 1: Fill the film canister 1/2 of the way full with water.
STEP 2: Place one of the Alka-Seltzer tablets in the film canister and quickly turn the canister so the top is on the surface and wait for your rocket to take off.

Explanation
Carbon dioxide gas builds up so much pressure it forcibly launched the film canister into
the air. With an Alka-Seltzer tablet, the carbon dioxide is produced as a result of a
chemical reaction.
