Science and electrical engineering types might have a list of practical uses for superconductors a mile long, but the rest of us really only care about how they can make things magically levitate. Just imagine if a company like Lionel revealed a levitating train set available in time for the holidays, the demand for Cabbage Patch Kids and Tickle Me Elmo would pale in comparison.

Unfortunately, while this tiny train set and its floating engine are definitely real, it's not something you can buy—yet. It's simply a science experiment designed to make those of us without access to superconducting magnets and vats of liquid nitrogen extremely envious. Mission accomplished.
