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 <shiver>.
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.

They said the incident was an "accident" that caused an unintentional chemical reaction and a temporary flash fire.
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.
