Probably a stupid question, but will we ever have something like a microwave to make things cold? Is there a reason this can't exist?

I had one of these when I was a kid.
It was annoying, though because you needed to fill it with ice and water. We used it very rarely. And IIRC one time we didn't dump the water out right away and left it overnight, and it never worked again.
