Faraday cage

Hey there kiddo! Have you ever heard of a Faraday Cage? It's kind of like a special shield that stops things from getting inside.

See, everything around us is made up of tiny things called atoms. These atoms have charged particles called electrons that move around them. Sometimes these electrons can cause problems, like when we use our phones or computers. These gadgets use radio signals to communicate with other devices, but sometimes those signals can interfere with other things.

That's where Faraday Cages come in. They're like big metal boxes with a bunch of tiny holes in them. When radio waves try to get inside the cage, the holes are too small for the waves to fit through. The metal shell of the cage also helps to absorb any electricity or waves that bounce around inside.

So, if you were inside a Faraday Cage and wanted to use your phone or computer, you could still use them without any interference from outside signals. It's kind of like being in a quiet room where nobody can bother you!

Pretty cool, huh? Faraday Cages are used in lots of different places, like on airplanes, in power plants, and even in some buildings to keep things safe from electrical interference.
