gas pump explosion

Gasoline pumps have all kinds of safety mechanisms built into them to reduce the odds of accidentally igniting them. They’re pretty good. I mean, how many times have you touched off an explosion while filling your car? But as reliable as they are, those measures are made to stop accidents.
And no engineer in the world ever thought about building them to stop angry young wizards.
It took a couple of seconds, but then there was a screaming sound, something metallic strained past the breaking point, and the first tank went up in a bloom of spectacular fire.
The explosion flung me back, scorching my skin and burning away the hair on my eyebrows. I landed on my ass—again—and lay there, stunned, for a few seconds. Sudden weariness, deeper than anything I had ever known, flooded over me in reaction to the energy I’d expended on my economy-sized ignition spell.
And then the second tank went up.
Hot wind and pieces of smoking metal showered against the front of the convenience store. I’m glad the first blast knocked me down. If I’d been standing, the metal shrapnel that punched out the entire front wall of windows would have gone through me first.
