Sure, your pet hamster's amazing leg strength may someday power a house, but can it beat you in a race? A pair of Chicago-based artists might be able to help you solve this mystery. The duo recently hooked up a homemade tachometer to a hamster's exercise wheel and mapped the data to a treadmill's motor. The fur ball's RPMs are transferred in real time, which gives it the ability to control its bipedal competitor's running speeds. The team cautions that no animals were harmed during this experiment, however a human ego may have been bruised after trying to keep up with a tireless rodent.
