one pendulum to another

One Pendulum to Another:

There is an interesting and amusing physics experiment which shows that vibrations, regular and repeated movements, may be passed from one thing to another. Make two small pendulums by tying weights to strings. Make the pendulum as nearly equal in length as possible.

     Tie a piece of string between two chairs so that it hangs between them. Then tie the two pendulums to this piece of string, placing them about 30 centimetres apart.

Ā Ā Ā Ā Ā Make sure that one pendulum is hanging straight down and is quite still. Then make the weight at the end of the second string begin to swing.
