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?

The problem is that cold is merely the absence of heat, you can't inject cold into something or generate cold, because there is no such thing as cold. It's kind of like how we can make a light bulb, but we can't make a dark bulb.
Maybe we could start manufacturing mini black holes to build the dark bulbs!
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.
