Yeah, that's what we get with our gas grill when the starter button don't work.
Turn the gas on full blast, step back a bit and throw on a match...
Reminds me of the time I needed to burn a twenty foot 'round pile of brush on the beach. Poured on about two gallons of gas all over and around it...
...did I mention that it was a really hot day...?
The 'ohnosecond' is measured as the time between when you start to strike the match and the time when it just barely flares and you realize that maybe this isn't a good idea...
But it did make an impressive mushroom cloud.
