I believe I mentioned tiny, neodynium magnets are available at most hardware stores, hobby shops, online, and probably from Don Fran himself. You don' teed nails........a thin piece of wire with a coiled, flattened end. These magnets are so powerful they will pick up a dollar bill, and pull iron out of fortified cereal. Larger ones are dangerous because the will get you skin between them and pinch the living crap out of it. Hey, I used these these all the time as a science teacher. If you want to see a really weird effect, drop one down a copper tube.
