Demos: 1S-38 Pendulum Wave

This demonstration, when started shows all possible phase relationships between pendula until it returns in unison to its staring position. These pendula make approximately 20 swings, some a little bit less and some a little bit more, in 20 seconds of time. Use the Initiator Stick to pull back all pendula simultaneously. Quickly remove the stick without disturbing the stand. The pendula at first will swing in phase, but since each one has a slightly different period (due to their length), their phase relationships will change. The sequential movement of the Pendulum Wave can be mesmerizing.
