Every week or so, he'd place some metal objects on top of a sheet of (specially treated?) dark paper, and set the bowl on top of it. By the end of the week, he'd have a "photo" of silhouettes of the items. Neat stuff, if not a little scary. A physics teacher of mine had a bowl that he knew released a tiny amount of radiation.

He had a meter that was meant to measure radiation (geiger counter?), and he dropped it inside this pot and it started going nuts. Now Im wondering if Im remembering this incorrectly, because it seems like a bad idea to bring a radioactive vase into a classroom.
