Yan sez, "It was really, really cold outside today (-29°F/-33°C) (With the wind chill factor), so I decided to use the opportunity to show my kids what happens when you throw really hot (boiling) water in the air outside at this temperature. Just seeing the look of wonder on my kids' faces was all I needed to justify going outside today."

It’s really cold outside today here on the south shore of Montreal (QC, CA). Really, really cold. The temperature outside currently is at -13°F (-25°C), but when you add in the wind chill factor, it feels more like -29°F (-33°C). Since it rarely gets this cold, I decided to use the opportunity to show my kids what happens when you throw really hot (boiling) water in the air at this temperature. You can check out the video of the experiment below (and put it in HD and full screen mode to observe the effect more closely.)
