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?

Nope that's unfortunately not how black holes work. It would essentially look the same as having the bulb painted black.

Practically speaking I think having a mini black hole in your home would look like being rapidly crushed to death.

I bet if you had a black hole with a wall on one side and a light on the other, it'd cast a really trippy shadow.
