A gas powered rocket

You will need: - 2 post cards - 1 film canister - 1 Alka Seltzer tablet - Sellotape and scissors

Instructions for launch:

  1. Fill the film canister half full with warm water.
  2. Drop in a quarter tablet of Alka Seltzer, no more.
  3. Snap the lid tightly into the canister, turn it over on a hard surface, and stand back!

The carbon dioxide released will make the rocket launch into the air. You may have to wait 15-20 seconds for it to take off. If you vary the temperature of the water, your rocket will shoot to different heights. The warmer the water, the higher it will go.
