How does a Helicopter fly?

A helicopter flies by using spinning blades that push air down, which makes the helicopter go up.

Imagine you're on a playground swing. When you pull your legs in, you move faster, and when you push your legs out, you slow down. The blades of a helicopter work like big, fast swings. They spin around really quickly, pushing air downward. This action is kind of like you pushing your legs outward to slow down, but instead of slowing down, the helicopter pushes the air so hard that it gets lifted up.

If the blades all spin in the same direction, the helicopter goes straight up. But if some blades move faster than others, it can tilt forward or backward, just like how you might tilt your body to move forward on a swing. This is how the helicopter moves around, by changing the speed of its spinning blades!
