[00:00:00]Ever wondered why microwave doors have this strange black mesh pattern? It's not just there to make the door look dark. It's actually stopping radiation.

[00:00:08]Inside a microwave, electromagnetic waves heat your food at high speed, but those waves should never escape the oven. That black layer is actually a metal mesh filled with tiny holes. The holes are small enough to block microwave radiation, but large enough for visible light to pass through. So, you can safely see your food cooking while the dangerous waves stay trapped inside. Without this mesh, microwave radiation could leak out, and that tiny pattern is what helps prevent it. So, that simple black mesh isn't decoration at all. It's a hidden safety shield you use every day. Did you know this before?
