Besides freezers I don’t think there’s any technology we know that could do this on a wide range of substances. But freezers are neat - they move heat from the inside to the outside and as they are insulated they can reach temperatures 40-50 degrees (Celsius) under their surroundings

I've been wondering this for my entire life

Given how much about science we still have to learn, I would say it is a distinct possibility. If you want something cheap and easy to use like a microwave to do this though, I highly doubt we'd see that possible for the next 30-40 years at minimum.

They trial'd something similar on the snowpeircer train instead of treats like ice cream for good behaviour they froze your arm off for being naughty lol

It's a good job they didn't have that when I was at school because I'd be just a head and torso now lol
