Micro freezer.
Basically a box like a microwave, but instead of heating it cools/freezes things very quickly.
Like...if you need ice cubes you put water into a tray & pop it in and in 3 minutes you have fully frozen ice cubes.
I have no idea how this would work & I only call it "micro freezer" because of it's similarity to a microwave.
