How do you make a rocket using ingridients?

To make a simple rocket, you can use a film canister filled with water and effervescent tablets (like Alka-Seltzer). Put the tablet in the canister, quickly seal it, and place it upside down on the ground. The chemical reaction between the tablet and water will create gas that builds pressure, causing the canister to pop and launch into the air. Remember to do this in a safe outdoor area.
