Explaining Particle Accelerators With a Vacuum and 1,000 Foam Balls

If you know what a "Time Projection Chamber" or "Proton Synchrotron Booster" is, you're probably a physicist. And if you can explain them to non-physicists, you're a hero. This complicated glass model attempts to make understanding particle physics a little bit easier--with the help of a vacuum cleaner and 500 feet of tubing.
