Okay kiddo, so you know how sometimes things can be hot like when you touch a stove and it burns your finger, right? Well, when things are cold, they don't have any heat and feel chilly to the touch.
Now, coldheat is a really special type of thing that can actually be both hot and cold at the same time! How is that possible? Well, it's made up of tiny particles called electrons that move really fast and create heat. But sometimes, these electrons are not moving in the same direction, which means that some parts of the object will have more heat while others will have less.
So, when you touch coldheat, you might feel a sensation of both hot and cold. This is because the parts of the object with more heat are hot, while the parts with less heat are cold. It's like having a hot and cold shower at the same time!
Scientists are still trying to figure out how to use coldheat in a useful way, but for now, it's just a really interesting thing to learn about. Cool, right?
