Shop Class: [1/30]

[manofthemullet.livejournal.com]

When the students arrive, they see the familiar backdrop of the scrap yard in place.

The only thing that would seem different about it would be the large pile of tennis balls sitting in middle of it.

"All right, kids. Today's assignment is to build a tennis ball cannon gun using items you might find here in the scrapyard."

ETA:

The following students will get detention if they do not supply an OOC or IC excuse for missing two classes in a row by next class period (Weds).

"Worth a try." John smiles and starts to get to work.

John looks around the scrap yard carefully. Finding a long, cylindrical PVC pipe, he cuts off the top half so he's got a pipe with an open top. The tennis ball rolls cleanly through it.

Next, he finds some rubber and checks the elasticity. It's good enough. He nails two ends of the rubber to one end of the pipe so now he's got some sling shot motion going on. He drops the ball at the end near the rubber and lets the rubber band go.

It doesn't work well as the rubber doesn't provide a lot of velocity going out of the pipe. John begins to wonder how he can get more power...

John finally decides to cut the PVC piping down so the travel distance is shorter for the ball and it gives the rubber more time to snap. He oils the pipe up as well.

Then, he actually ditches the rubber and finds an empty, plastic tube that's covered on one end and open on the other. He inserts the open end onto a newly closed, short piece of piping with two open ends, trying to go for an air push this time.

He pulls the container back to the very end and drops a ball into the opposite end of the pipe. Then he pushes down on the plastic container and the ball shoots out. Again, not very good but this is hard!

"Good Job, Crichton. Well thought out."
