The Woodson teacher either:
1. left the methyl alcohol container open, near the flame, and it spilled - instant fire ball
or
2. tried to add alcohol to an already burning petri dish - flame jumped into the methyl alcohol bottle, ignitied, and she threw the burning bottle like a crazy woman into the air where the fluid sprayed everyone.
did not follow directions.
