I heard hot water freeze faster when thrown in freezing cold air, because it evaporates faster - making smaller droplets and increasing the surface area
We did an experiment in university where we cooled distilled water, which was completely still.
We managed to get the temperature down to -7C I think before it froze. It quickly rose to 0C when it started freezing. kinda cool.
I’ve seen youtubers repeat the experiment, think it’s called supercooling. It also causes longer time to freezing, and was one of many theories for the Mpemba effect

Right, I can believe that. I was thinking of making ice cubes, which is also something I heard.
This is actually a thing, it’s called the Mpemba effect. It’s hella weird (that’s the scientific term), but can be reproduced in experiments.
