The purpose of this project was to make something the would scatter
paricles in 2D. We send several samples out and collect them some how
with pockets or paper cups with this example. My used some slingshot
pellets as my particles and released them at once down a little ramp onto
a flat cardboard surface. I placed three different shapes on the surface
to demonstrate the scattering and then caught the pellets with the paper
cups.
