How Does Sailing Across the World's Oceans with No Tech Work?

Sailing across the world’s oceans with no tech is like using a paper boat and wind to go from one side of a big lake to the other.

Bold ships are like big, strong boats made of wood or metal. They’re built to float on water and move when wind pushes them. People who sail use something called a sail, which is like a big piece of fabric that catches the wind and helps the boat go faster.

Imagine you're in a playground, and you're holding a paper airplane. When you blow on it, it flies, that’s how sails work! The wind pushes against the sail, making the ship move forward. Sailors can change direction by adjusting their sails or rudder, which is like the tail of the boat that helps steer.

Sailors use the sun and stars to know where they are, it’s like using a map in the sky. They also follow currents, think of them as invisible rivers in the ocean that carry boats along without extra effort.

So even with no tech, people can go from one side of the world to the other, just like how you use wind and water to play on a lake!
