Reaction ferry

Okay kiddo, have you ever seen a ferry? It's like a big boat that carries people and cars across a body of water. Now, have you ever heard of a reaction? It's when something happens because of another thing that happened before it.

So a reaction ferry is like a special kind of ferry that doesn't use an engine to move across the water. Instead, it uses the current of the water to move from one side of the river or lake to the other. The ferry is attached to a cable or chain that stretches across the water.

When the ferry is ready to move, it turns its bow (the front part) towards the current of the water. As the current pushes against the ferry, the cable or chain pulls the ferry across the water to the other side. The weight of the ferry helps it to move, and the current of the water pushes it along.

Once the ferry reaches the other side, the crew turns the ferry around, and it goes back to the other side. It's like a big swing that goes from one side to the other. People and cars can get on and off the ferry while it's moving, just like on a regular ferry.

Reaction ferries are cool because they are very simple and don't use any fuel or electricity to move. They are often used in places where there isn't a bridge or where the water is too shallow for a regular ferry. So next time you're near a river, keep an eye out for a reaction ferry - you might just see one in action!
