I remember match flicking back in the day, and stupidly enough, deodorant flame throwers. One thing that was safer and more "intresting" was spraying patterns on concrete pavements then quickly lighting them, it looked ace. And road cones, spraying the inside of those then lighting the end, it made a big "whoomb" noise and shot a jet of flame out! Ah, being a teenager wasn't so bad thinking about it. :lol:
That said, I would advise fire playing with to be done very rarely if you really must do such things, I know warning people is pointness because I was warned and never listened... lads'll be lads and all that. It's better to just say "if you're gonna bugger around with things like that be bloody careful!".
