Most kids learn the hard way about playing with gasoline. I know I did.

The scariest thing is that the gas vapor creeps along the ground and 'climbs' things...like legs, trees, and walls. When it ignites, all the vapor goes explosively.

In elementary school I was friends with a real live firebug pyro. The kind of guy that rode his bike around town with a little bottle full of gas and a Bic lighter. I stopped hanging around with him pretty quickly.

To this day I have a sneaking suspicion that he's probably killed someone by now, knowing the kind of 3 alarm stuff he'd pull.
