Killer, it is Want not Wont… Anyhow you need dust for it to freeze. The clouds in the sky are a mixture of dust and water, and becasue it is so cold up there it freeze in to snow, before it falls. And once the small particals of Ice become too heavy thay fall down to earth and warm up to become water again. The only reason the bottles of water didn’t freeze in that blokes freezer on youtube was becasue there was no dust iun the bottles. It was purified water so the water couldn’t cling onto anything for it to freeze.
