Thanks all!å

I missed the October 2018 incident.

I have only ever done this demo with conc sulfuric and sugar.å Looks like someone created this variation with solvent to omit the conc sulfuric and it is causing problems. Duh....

The version here uses solid camp stove fuel - not liquid fuel.

...and here we have switched to lighter fluid with no safety (except Peter's comment today!å Thanks Peter).

I was told that this was on the news tonight, but I can't find out what day it occurred.
