This cold weather science experiment has been around for decades, and home videos are all over Youtube. You'll never see it done in Florida, since the temperature should be below -10F and ideally -25F. The permise is this. Take a glass or pot of boiling water and throw it into the bitter cold air. The water changes state from liquid to solid(ice crystals) before it hits the ground! This experiment works best if the water is near the boiling point, and the colder the better. Here are a couple of home videos. I tried it here in West Palm the other day but it just made the ground wet...
