Procedure

1^st we brainstormed about how we were going to design it and which angle was like the best angle to launch a cannon.

2^nd we got the materials which were 2 tennis ball cans, 18 inches of tape, scissors

3^rd the first step in actually building the cannon was cutting the rims off the tennis ball cans. We did this to both of the tennis ball cans using the scissors.

4^th once the rims were gone we cut one of the tennis cans in half. Taking one half of the tennis can we cut it so there was a slope. That was done so we could like use it to lay the main body of the cannon (other tennis can) on it sort of like a base

5^th we took the other half of the tennis can and trimmed it down about 2 or 3 inches, so that when we laid the cannon body( other tennis can) on the slope the end of the cannon could rest on that.

5^th after everything was cut and the angle was finalized we used the tape and taped it together.
