A No-Fuss Particle Detector: An Inexpensive and Robust Way to See the Invisible

There's nothing like particle physics to make you aware that we exist in an endless three-dimensional pinball game. All around us, subatomic particles arc, collide, and barrel along with merry abandon. Some originate within our own bodies, others come from the far ends of the cosmos. But detecting this invisible tumult requires equipment, which can be costly. I wanted to create a way to detect at least some of the pinballs for less than US $15.
