- Colourful construction paper
- Camera film canisters - 1 per rocket
- Drinking glass
- Safety goggles (strongly recommended)
- Chewing gum - 1 piece per rocket
- Alka-Seltzer or Airborne tablet - 1 per rocket
Step 1: Cut a piece of construction paper that's roughly as long as the film canister, and wrap it around the canister so that it is completely covered. Secure with tape.
Step 2: Using the drinking glass, trace a circle on another piece of construction paper, and cut out.
Step 3: Roll the circle into a cone-shape and tape it to the end of the canister that does not have the lid.
Step 4: Decorate your rocket however you like: you could use stickers or markers, and even cut out fins from the construction paper to attach to the sides.
Step 5: Chew the gum, and then stick it on to the inside of the canister lid.
Step 6: Cut the tablet that you are using in half, and firmly stick on of the halves into the chewing gum.
Step 7: We recommend putting safety goggles on for this part: Fill about 1/3 of the canister with water, and then tightly snap on the lid.
Step 8: Find a flat surface to launch your rocket off of. When you are ready, quickly flip the rocket so that it is standing on the lid end, and then step back. After 30 seconds - 1 minute, your rocket should blast off!
