You know what isn’t great? When the weather is so cold outside that morgues go out of business. When the temperature drops down to -13°F (-25°C), and then feels even colder, around -29°F (-33°C). Sure, it gets worse in other places, but for the sake of a Geeks Are Sexy writer, whom we’re vicariously living through for this story, those are the particulars. I can count on one hand how many times I remember seeing snow in Louisiana, where I live, because the temperature rarely drops down into the twenties, much less the negative twenties.
And I wasn’t complaining about that until I saw this video of boiling water turning into snow. Granted, I’m perfectly happy not having to shovel snow in order to drive on snow, so I would just want to visit someone’s snowy area in order to do accomplish this feat of natural magic. You’ve done it again, science, you old cad.
Any amount of boiling water should work, though I’d suggest using a thimble-full until you’ve got a handle on the situation. Obviously, don’t try this without being damned sure the temperature is cold enough, and even if you do, throw the water away from you. I’m not sure what would happen if you threw cold water, exactly, but the hotter the water the better, since the molecules are in flux and set for evaporation, and it immediately turns into water vapor as the droplets hit the cool air.
The next obvious step is coming up with a costume for yourself. Your name will obviously be something clever and fear-striking, like S’No Problem, or Pain Below Zero or something. You may want to work on more powers than just the snowy smoke screen though.
