Thanks, Rob, for the nice collection of articles and information. If it?s boric acid and alcohol, it?s what we call Borate Flame (lovely green flame). Others call it flaming tornado We?ve re-engineered the demo to use an Erlenmeyer flask and a Buechner funnel ? if you want the details, let me know off-line. Birkett's hypothesis: "Any chemical reaction From: ACS Division of Chemical Health and Safety Doctor says boric acid and alcohol: http://fox17.com/news/local/doctor-science-experiment-with-borax-alcohol-caused-hendersonville-students-injuries Appears to be the Rainbow.

Bush said the students were gathered around as the teacher did a demonstration that involved mixing chemicals.
There was a sudden flash fire lasting 3 ? 5 seconds. Because there was no smoke it did not set off any fire alarms.
Bush confirmed the students have second degree burns, consistent with a flash fire caused by a chemical reaction.
Every news outlet is calling this an ?experiment? and/or accident when, in fact, it is neither.
