Bootcamp's right, if you leave gas out in the open for a long time (dont know how long, but obivously until they are no more vapors) you can throw matches and stuff in it and nothing will happen. I read it in a book, but i would not try it.
As the old saying goes "Play with matches, you'll get burned." In this case, mess with gasoline, you could be blown up.
