Okay, so you know how things get colder when you put them in the fridge or the freezer, right? Well, scientists have discovered something amazing called superconductivity!
Superconductivity is when electricity passes through certain materials with zero resistance, which means it can travel without losing any energy or getting weaker. This is important because it could help us make better electronics and save a lot of energy.
But, here's the thing: superconductivity normally only happens when the material is very, very cold. Like, even colder than a freezer! This is because these materials have to be cooled to a certain temperature in order for the electrons (tiny charged particles that make up electricity) to move around with zero resistance.
But recently, scientists have been trying to find a material that can be a superconductor at room temperature, which means we wouldn't need to cool it down so much. This would be really amazing because it could revolutionize the way we use electricity!
Unfortunately, it's been really hard to make this happen. Scientists have tried all sorts of different materials, but none of them have worked yet. But they're still trying! Who knows, maybe one day you'll be able to plug in your phone to charge without having to worry about wasting energy because it'll be powered by a room temperature superconductor!
