Machine With Concrete

Arthur Ganson is a kinetic sculptor who builds “Rube Goldberg machines with existential themes”. One of his works is called Machine with Concrete, which demonstrates the magic of gear ratios

According to a piece in Make, the input shaft spins at 200 rpm, which is reduced by gearing down to 1 revolution every 2 trillion years by the time you reach the gear on the end…which is so slow that even embedding the final gear in concrete doesn’t make any difference to the machine’s operation.
