If anybody’s wondering what’s happening here, this clip made it onto Outrageous Acts of Science, and they explained that this teacher was demonstrating the Leidenfrost effect, which is basically when you place a droplet of a liquid on a surface that’s far hotter than its boiling point. The part of the drop touching the hot surface turns into vapor and forms a cushion that the rest of the drop rests on top of, which causes it to skid across the floor so quickly. The substance the teacher uses in the video is liquid methane. But methane has a really low boiling point. Like, about −160 °C low. So once it touches the comparatively hot floor, the Leidenfrost effect comes into play, and it slides across the floor. The issue is though, methane is colorless, so you can’t normally see it. Thankfully (in this demonstration), methane is also very flammable, so he sets it on fire before dumping it onto the floor so you can see it as it moves. Definitely a cooler demonstration of the Leidenfrost effect than dropping a little water in a hot pan. Or hotter, if you like puns.
