perpetual motion machine. Lift and drop the lever to make all pendulums start moving. The shorter the length of the pendulum, the faster it swings. The longest swings 15 times in 30 seconds, the next 16 in 30 seconds and so on. This causes a pendulum to swing opposite the neighbour pendulum after 15 seconds and all pendulums to swing together after 30 seconds.
