what happens if you light it a 2nd and 3rd time?

Compare rate of combustion for different types or concentrations of alcohols. Also examine how the whoosh bottle changes after successive lights.
Note: This was one of the first videos I ever made and have never posted it! It was fun to make and it is fun to see some progression in my filming (if not a tremendous amount) For more up to date whoosh bottle experiments and combustion analysis check out the links below.
