It's good to see that it's possible but I think it goes against everything a person has ever learned in life. Its like people who are afraid to touch an electrical wire even if its not on. I know there was gas in there, I know I would be applying copious amounts of heat, I am afraid of explosions and shrapnel in my chest...
