swimming plastic fish



Has anyone opened up a "magic aquarium" toy? I assume that the
independantly-swimming fish contain small magnets. Are they driven by a
motorized permanent magnet in the base? This would use lots less energy
than a switched coil.

This is for an "ask a scientist" question from madsci.org.
