Spectacular prepared fifteen pendulums monotonically increasing lengths and put them to oscillate. Soon enjoy traveling waves, standing waves and random motion.
However, the design of the multiple pendulum can not be left to chance. As revealed from Harvard , a period of one complete cycle is 60 seconds. The longer the pendulum swings 51 times in that time, the length of each of the other clocks is adjusted so that each one of them every minute swing again as above. After 30 seconds, half of the pendulum is at the maximum amplitude to the right, the other half at its maximum amplitude to the left. When you go sixty seconds, all have completed an integer number of oscillations, back in sync and the beautiful dance begins again:
