Table on Fire #1 0708

I do a set of demonstrations showing factors that affect the rates of chemical reactions. This one here shows the affect of surface area. It starts out pretty boring as I light alcohol in an evaporating dish [which was not independently filmed]. I then pour the same amount of alcohol out on the table and it is clearly seen that the alcohol on the table burns faster because of its large surface area. The fire stops when it runs out of alcohol, but it can be seen that the fire in the evaporating dish is still going. This serves as a segway into the another factor affecting reactions: amount of reactant.
This demonstration was preformed on a fire proof table surface with an alcohol [which burns relativly cool] under controlled lab conditions with the audience a safe distance away and the instructor taking all safety precautions. The teacher that taught me this demonstration had a student attempt to recreate it once in his faterh's garage with gasoline and was lucky to get out with his life and have the only damage being a burnt down garage. Do NOT try this at home.
