On November 12th, 1717, clockmaker and mechanic Johann Bessler placed a 12-foot diameter, strange-looking wheel into a room. With a tender push, he started the contraption rotating, then confidently turned and strolled outside. Guards promptly secured and locked the door behind him. Nobody would be allowed to enter the room for two weeks, lest the machine be tampered with. Perpetual motion machines are finicky gadgets, you see. Lo and behold, two weeks later the door was opened
stanley cup becher and the wheel was found to still be turning. The room was sealed yet again, this time not to be opened for 39 days. Surely this time physics would apply its grating touch, halting the wheel. No machine can continue operating forever after all, at least not without some external force pumping in energy to surmount the reins of friction. Again, when the door was o

Bessler was happy to explain that the machine functioned using a series of weights to keep it perpetually unbalanced, and thus moving. But was his machine physics defying, or a c

The key, most surmised, was to make one side constantly heavier than the other, causing motion in the direction of the weightier side. Simple, right Not exactly. None of the
