bars do NOT sell pure grain alcohol
beer, wine, and whiskey are NOT FLAMMABLE
100 proof (50% alcohol/aqueous solution) WILL NOT BURN OR CATCH FIRE
if you throw a small amt of whiskey on a large fire that is making enough heat to vaporize the alcohol, it will make a small momentary poof
i challenge anyone to post a vid of them setting a shot glass of whiskey on fire with their bic lighter
