When I was younger I built a tennis ball launcher... It was a pro job and needed a few tweeks... I built it out of about 4 or 5 layers of pvc pipe. Then it was wrapped in fiberglass. Glad I didn't have it next to my head. Electrically fired... Was impressive. I shot it straight up. I set the gun down and started walking around picking up pieces of the pvc. Then I heard a thump. The tennis ball came back to earth. All the fuzz was burned off black and the charge blew a hole in one side and out the other. Played with it a little more and gave up on the idea... Someone was going to get hurt. Maybe someday I will talk about my battery cannon...
