If you love the idea of creating your own instant miniature batch of snow and have the right conditions, then you will definitely want to see it in action with this video. And even if you happen to live in a warmer climate this video is still awesome to watch…bring on the instant snow!
From the blog post: The key to the hot water’s fast-freeze here is not just the large temperature difference, though. It’s the fact that the water is being tossed. When the water leaves the pot, it tends to break up into droplets, which quickly increases the surface area exposed to the cold air, and the rate of heat transfer depends on surface area as well! A smaller droplet will also freeze much more quickly than a larger droplet.
