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?

Cool question. Iβd imagine the easiest way I can at least think of is spraying it with liquid nitrogen. The challenge will be to get the nitrogen back in the bottle and keep it liquid in the meantime.
I think that'd shake out to being an air conditioner with nitrogen as the "air." You'd lose some nitrogen every use, but nitrogen is cheap.
The problem is your piece of pizza would become as brittle and sharp as ice, and likely to injure you if you handled it.
Who wants to cool pizza? If imagine this would mostly be used on drinks, or frozen treats like the ice cream in their picture.
Terrible use for ice cream too, actually. Flash freezing it and not whipping it at the same time totally ruins ice cream.
Ah brick of frozen milk... large ice crystals to crunch on and a surface like concrete. My favorite kind of ice cream
Properly flash-frozen ice cream is actually very smooth since the ice crystals are very small. The water freezes before it has a chance to form large crystals.
Neat. I mean makes sense considering dip n dots
wouldn't you just get a huge dipping dot?
Haha probably, but it was the only thing I could think of that people would want to be cold faster. Maybe some other desserts, like lemon meringue or banana cream pies.
Iβm baffled our usernames only differ by one letter. My idea was, if you βsprayedβ the item from afar, it would cool the surrounding air and only ever so slightly touch that item. I donβt think this would flash freeze it. Feel free to correct me.
