Curiously Strong Magnets

I didn't post about these earlier because I didn't know just how cool they really are -- even though they come with the following warning:

:: DANGER WILL ROBINSON :: DANGER ::
These magnets are very strong and should be handled with care. Small children should not handle these magnets. Older children should be supervised at all times when handling these magnets. These magnets should not be ingested. If the magnets are allowed to snap together or against steel, they will chip and crack. You should keep them at least six to twelve inches away from computer hard drives, credit cards, computer monitors, and other susceptible electronic equipment. Individuals with pacemakers and other internal medical devices should not handle or come within close proximity of strong magnets. These magnets are safe for air transport as packaged but as a general rule they should be kept off airplanes.

Each set contains 87 grade 40 neodymium-iron-boron rare-earth permanent magnets plated in nickel. Get your own, 'cuz I'm not giving up any of mine.
