Pendulum

How it works

• It is a bob on a rod, let go at the start of the run and swinging under gravity.
• Its power is on for half of every swing, and off for the other half.
• The first pulse comes a short way into the first swing.
• The bob keeps swinging for a long time, and it knocks light things away. A bowling ball is too heavy and stops it.

Tips

• Pick this one for medium timing. The size of the swing barely changes the speed.
• Keep the swing's arc clear of parts that would stop it.
