How it Works

You have to pull on a chain every half hour to keep the Non electric ceiling fan running. When you pull the chain down, a weight is sent back to the top. As it turns, the weight works its way back down and makes the blades turn.

The Science of Its Action

As the weight falls and turns the fan, the Non electric ceiling fan is doing work on the air and raising the temperature of the air. However as the air moves faster, it gives up energy, which cools the air around you.
