Cannon Design: Materials and Procedure

Materials
1. 2 tennis ball cans
2. Scissors
3. 18 inches of packing tape
4. Protractor
5. Compass (mathematical)
6. Ethanol
7. Nerf ball
Procedure
1. Cut off about 1/3 of the top of one of the tennis ball cans.
2. Tape the 2 cans' lids to the sides of the can that has been cut; this will stabilize and balance the cannon.
3. Make sure that the cannon is at a 45 degree angle
4. Poke a small hole into the topside-bottom half  of the cannon with the compass; this will be used to put the drop of ethanol into.
