Make your own rocket launcher for your backyard.
These 'rockets' will go up to 20 ft in the air. The power for these rockets
comes from the gas created by combining two common items.
For Parents: Be sure to supervise your children for this activity.
The film canister explodes out of the launcher with enough force to cause an
injury if kids are looking into the launcher.
Materials
1.styro foam plate
2.toilet paper tube
markers
tape
3.white camera film canister
vinegar and baking soda
or alka-seltzer tablets
Instructions:
Use the markers to make a design on the toilet paper tube (rocket launcher).
Tape the rocket launcher to the center of the plate.

Put
the rocket fuel in the film canister (see note below).
Quickly put the lid on the canister, and drop it into the launcher, lid side
down.
STAND BACK!
Rocket will launch (usually 10-20 seconds).
Be sure to wait at least a minute before checking on the rocket if it
doesn't launch.
Rocket Fuel
Vinegar and Baking Soda - put 1 tbsp of vinegar in the film canister. Hold
it near the launcher and add 1/2 tsp baking soda. Quickly snap the lid on
and drop into the launcher lid side down.
Alka-seltzer - Put 1 tbsp. water into the film canister. Add 1/2 an alka-seltzer
tablet and quickly snap on the lid. Drop into the launcher, lid side down.
Note: White camera film canisters work best due to how the lid snaps on.
Results may not be as good with other types of canisters.
Warning: Parents, be sure to supervise
your children when they are launching rockets!
