How much do I love United Nuclear? Where else on the internet can you buy Uranium, Cloud Chambers, and magnets strong enough to break bones? Nowhere that I know of. This is not a joke, it's an actual science supply store. Use at your own risk."Two Super magnets can very easily get out of control and break fingers and even your arm if opposing poles fly at each other. If working with multiple Supermagnets, always handle one magnet at a time, secure it, then proceed to the next magnet."
