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? (lemmy.dbzer0.com)

Cool question. Iβ€˜d 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

    Iβ€˜m baffled our usernames only differ by one letter. My idea was, if you β€žsprayedβ€œ the item from afar, it would cool the surrounding air and only ever so slightly touch that item. I don’t think this would flash freeze it. Feel free to correct me.
