Pendulum Wave

Nine pendula, each having a 2-line mount, vary from slightly less to slightly more than 20 swings in each 20 seconds. With a simultaneous start, the bobs make a very captivating wave-like parade that shows all the possible phase relationships before returning to unison and starting over again. The rigid interlocking frame is 55cm wide and 48cm high and provides offset sharp edges to support each pendulum.
