Constant Science: The Curious Case of the Color Cannon
Today we have a Very Special Episode of Constant Science. A while back my mom asked me to help her build a cannon that would spray color powder all over the place so she could use it, well, to spray color all over people. She runs an organization in Marion, Indiana called Cancer Services of Grant County. They're a non-profit that provides consulting and aid to people in Grant County who are afflicted with cancer, and Saturday, 10/3/15 is their annual Color Me Pink Fun Run.
Normally they just throw the color powder at the runners but she wanted to get a little fancier this year so I used my experience in building random stuff and my knowledge of physics and fluid dynamics to help her out. Here are the results!
