I just saw this, and I am totally aghast!

Perhaps someone (president? board of directors? ) from DCHAS and/or the ACS should contact MSN to 1) update them on the various flaming tragedies that have recently happened during 'safe' demos; 2) ask them to pull the video. It's one thing when it's on YouTube, quite another when it is being 'hosted' by what I would normally consider a reputable news source.

Are the safety folks the only ones who can use google for finding "high school chemistry lab accidents articles"? I swear everyone else must be using it for sports scores, following the Kardashians, etc

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...
