Woodward effect

Okay kiddo, have you ever been on a swing set before? When you swing high, you fly forwards and backwards through the air, right? Well, imagine you have a toy car on a track and instead of pushing it, you pull it back like it's on a swing. When you let go of the car, it doesn't go back and forth like a swing. Instead, it actually moves forward, faster than if you had pushed it, and using less energy.

Scientists call this the Woodward effect. It's a bit like magic! But, it has to do with something called quantum mechanics. You don't have to worry too much about that. Just know that it is a way to make things move faster without using as much energy.

So, why is this important? Well, scientists use this effect to build really cool things like rockets. They can make the rockets go faster without adding extra fuel, which means they can go further into space and explore more things.

Isn't science awesome?!
