How It Flies
Imagine you're on a merry-go-round, but instead of holding the bar, you're twirling your arms really fast. That's kind of what happens with a helicopter’s blades, they spin around, pushing air down like a big fan. The air pushes back up, helping the helicopter lift off the ground, just like when you jump on a trampoline.
If you want to go forward or turn, the blades twist differently on each side, like how your arms move in different directions when you swim. That’s how the helicopter moves around, it’s like being able to dance in the sky!
A History of Flying Machines
Long ago, people dreamed about flying, just like kids today might dream about becoming astronauts. The first real helicopter was made by a man named Igor Sikorsky in 1939. It looked very different from today's helicopters, more like a metal bug with big spinning arms.
Before that, there were even earlier flying machines, like the ones Leonardo da Vinci drew on paper, kind of like how you draw your dream robot on a napkin! So, helicopters started as a fun idea and grew into amazing flying machines we use today.
Examples

- Helicopters are used by firefighters to drop water on tall buildings.
