Brownian motor

A brownian motor is a tiny device that can work like an engine. It takes small, vibrating particles and uses them to move objects in a particular direction. To do this, the particles have to have a certain pattern of vibration. Think of the particles like popcorn kernels bouncing around a pan on the stove - if the kernels are bouncing around in a certain way, the popcorn might move in one direction or another. The brownian motor does the same thing, but with tiny particles instead of popcorn kernels. Those particles move in a pattern which pushes the object the motor is connected to in a particular direction. It's like a machine made from tiny particles!
