Piston

How it works

• It pushes its head out while its colour's power is on and pulls it back when the power goes off.
• It does this each time the power changes, so a pendulum or a switch can work it again and again.
• Its push is limited. A heavy load slows it, and an anvil stalls it.
• A light ball on its head hops off at the top of the stroke.

Tips

• An anvil is too heavy to lift, but a bowling ball is not.
• Pair it with a pendulum or a switch to work it over and over.
