All I can say (right now) is that this video shows complete lack of regard for safety.
Sad to say that someone will attempt this and someobody will get hurt.

[DCHAS-L] Liquid methane experiment in class
I think DCHAS members may want to be aware of this in case they have people who like to emulate Internet videos in the organization...
This teacher leaves his students treating the floor like lava while leaving them in awe and he shows them what a little bit of liquid methane will do when lit on fire and poured onto the floor. Perhaps there's an opportunity to develop a Job Hazard Analysis of this demonstration...
