Liquid marbles

Liquid marbles are like tiny balls made of a liquid and a solid. Imagine you have a little bit of water in your hand and you try to roll it into a ball - that's kind of like a liquid marble. But instead of just using water, scientists use special powders that make the water behave differently.

The powder makes a thin layer around the water droplet, kind of like a protective shield. This makes the little ball of water much more durable and stretchy. Imagine you have a balloon and you blow it up but don't tie it. You can stretch the balloon without it popping because the rubber is strong and stretchy. Liquid marbles work in a similar way - the powder makes the water stretchy so it can be played with without breaking.

Scientists love liquid marbles because they are special - they can hold tiny amounts of liquids without letting them spill out. It's like having a tiny cup that you can carry around without spilling!

People have come up with all kinds of cool uses for liquid marbles. They can be used to carry medicine or chemicals that need to be kept safe. They can be used in experiments to test how liquids react to different surfaces. And they're just really fun to play with!
