ok im not condoning this or saying I am going to do this. I am stating this as corrections to some comments on this thread. First of all, the heat from the flame is coolest at the very bottom in the middle, (from my high school chemistry teacher) hypotheticaly there is no heat at the bottom in the middle. The tip of the flame is the hottest part of the flame. Second, bunsen burners, (you spelled it right finnish) use lots of gas under pressure, which most likely can't be stored on, or in the armor. Third, as long you have the tip of the burner above the actual helmet and not where the flame can touch any of the helmet it wont melt the helmet. Fourth, I think as long as the resin has cured its very hard to actually light on fire and melt. Fifth, the formula 1 race gear is fire retardant, not fire proof. which means it can withstand heat and not burn whats behind it. A continuous source of heat, such has a bunsen burner, would burn through that. Sixth, the construction of a bunsen burner is too tall to fit in a helmet as the tube has to be long enough for the gas and oxygen and gas to mix correctly for the right flame. IT IS NOT EVEN REMOTELY A GOOD IDEA DO NOT TRY THIS EVER UNLESS YOU ARE PLANNING ON DYING A HORRIBLY PAINFUL DEATH. Again these are all completely separate situations. If put togethor it is hazardous to your health and those around you.
