My idea is for housekeepers, I think. Do you know the situation when your drink is too hot to drink it.... It is very strange situation and uncomfortable, especially, for children. I have one idea.... What about micro frizzier.... If you need something to be cold you can do it with a help of this thing. If you need some cubes of ice you can just use this micro freeze. It will work as micro wave but the other way! Good for Coca-Cola.
