Following the lead of a few others on this list, I also provided my feedback on the MSN site. It will only address the fact that MSN has posted the video, but at least it is something and perhaps the video will be removed if there is enough feedback to point out how irresponsible the video is.

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...
