If it's cold enough, and you throw a cup of boiling hot water in to the air, every bit of the thrown water will turn in to something like snow, and no liquid comes back down. It seems like the size of the flung water droplets is important, like if the water is thrown more vigorously the effect is more pronounced. I wintered at the South Pole in 2014, the year the ALS Ice Bucket Challenge was a big thing. One of our crew did it, outside. We discovered a similar effect: when it's even colder out, maybe -80s F: ice water makes what looks like a cloud of steam - in the video (sorry, can't find it quickly) it looked a bit like he was cheating.
