Finally some info on the actual demo that burned four students back in
December.
This is taken from the listserve of the Division of Chemical Health and
Safety of ACS, May 22, 2012.
As I think most of you know, the demo does not consist of someone¹s dropping
a ³match into a jug of methanol,² as the news report said.
The ³methanol cannon² and other related demonstrations involving combustion
of various alcohols [or other flammable liquids] have apparently been
involved in many accidents resulting in student injuries. For example,

MAPLE GROVE, Minn. - The Osseo School District is making changes to its
teacher-led science demonstrations after four students were injured in a
classroom accident several months ago.
In the 71-page report, the methanol demonstration that burned the students
back in December will not be allowed pending further review. It has not been
used in the classroom since the accident.
It's called the "Whoosh - Flash Bottle" demonstration where someone drops a
match into a jug of methanol.
The report also calls for a more stringent approval process for science
demonstrations, a detailed list of approved demonstrations, and all
secondary science teachers will now have to watch videos on science safety.

Be safe!
