Do you have a flamethrower?
The question is... do you want to buy one?
Ah, Salty I will have to look into a fix for that. Thanks man.
Depends on the fuel and price
We always used to use super soakers loaded with gas and it will work till the tip melts
or
Poke a whole in the top of a pepsi bottle with a nail, fill half full, light the tip and squeeze for fun! I caught myself on fire twice in one week with this method though (last time burnt the shit out of myself.)
Do no try either of those methods at home. I will see what the legality of a actual backpack flame thrower is lol....
Edit: Thinking back one time was a friend who got me and the other time was myself... dumb kids...
