proof?
also most flammable liquids need a hell of a lot more than one spark to ignite
Elementary common loving sense buddy.
Gasoline is flammable.
Sparks set off flammable things.
Sparks hitting gasoline will ignite it.
WOOOAH ITS A loving REVELATION
gimme proof that gasoline explodes instead of, say, catching fire
Common sense again. If enough of a flammable liquid is ignited at once it will cause an explosion.
