Fan (mechanical)

A fan is a machine that helps move air around. It has blades that spin around really fast, and when they spin, they push the air in one direction. This makes the air move and creates a breeze.

You can use a fan to keep yourself cool on a hot day, or to help circulate air around a room so that it doesn't get too stuffy.

There are different kinds of fans, like ceiling fans or desk fans. Some fans are really big and can cool entire buildings, while others are small enough to fit in your pocket.

Fans use electricity to work, and you can turn them on and off using a switch. Some fans also have different speeds, so you can make the breeze stronger or weaker.

Always be careful around fans, as the blades can be very dangerous if you touch them while they're spinning.
