pic: My POE Ballistic Device Project

[Kyle Love]

Here are some more pictures that might be able to answer some questions some of you might have. I would like some constructive criticism from all you guys. Even though the project is over and I got a 100/100 I want to make it even better. Do any of you see a way of how I could?

PS If you guys have extra time, build one of these things! ITS A BLAST!

Was it accurate (distance and side to side)?

We were not told the distance we had to shoot until we walked into class today. So, during our test days we took several measurements between the 5 and 15 foot range that he could have tested us on. It ended up being 13 feet.

We shot it really straight. After we finished building it I was concerned it would hook, like a paintball gun. But after testing it surprisingly shot dead straight.

I teach the POE class as well. In my class, my students must make their device to be accurate. They can shoot three times, and they are to land at the same spot each time. To be able to shoot for distance is easy, but to be able to consistantly land the ping pong ball in the same spot is the hard part. This is a very cool project because the students must be creative in their design with materials they supply, all while keeping it within a 1 x 1 square footprint.

As stated above, we had to have accuracy in the actual test.

i havent done this before, but am about to for my POE class. finding this is part of my "identify the problem/research current solutions" interesting... im thinkin bout doing somethin similar making something like a spring powered cannon-esque launcher. i also worried about the ballistics of a ping-pong ball and arching like a paintball, but i guess that wasnt an issue here?
