I cannot believe it was actually a lighter; I blew up a fair number of lighters during my pyromaniac youth and never witnessed anything remotely like the explosion in this video. You get a pop and a flash - it's not especially dangerous. This looks like it had to have been a much larger mass of fuel inside a pressurized container.
