Never mind - I found it. I think they need to update their video. I did not watch the whole thing, but some obvious omissions in safety.

It saw this too.  It made me wonder if the approach we, the ACS, is taking is the correct approach.  In addition to teaching the safe way to show the demonstration we need to discover where this teacher learned how to do this demonstration, follow the trail back to get to the source of the demonstration and correct the problem.

Hi All,

Here we go again. Another flammable demonstration gone wrong.

This was reported on ABC National News tonight (Nov 2). It happened in Georgia this week.

Fortunately, the teacher was not seriously injured (minor burns and burned hair) and none of the students were hurt.  One very, very lucky teacher!

I guess she was trying to show that flame will follow a vapor or that the vapor had a higher density than air.
