My college roommate managed to set his jeans on fire (they were frayed, and I guess a couple of loose threads managed to ignite.) ---

> [@Jman](#): > > I guess my farts had too much stuff in them…I never got blue…always bright orange. well i actually did this last night. Mine also turned out orange, but i did it through my boxers. If i remember my grade 10 auto and chem classes, I think it turned orange because the Air/Methane mixture had too much air in it since it took time for the fart to get through my boxers. I assume if you do it with out any boxers and a really GOOD friend to hold the lighter without burning you it would turn blue because there is less air. Then agian, i passed chem with a 56 and my auto mark wasnt that much better. If im wrong, please correct my ignorance;) ---

Never, ever light a fart in a pair of polyester pants. :eek: ---

From the Wikipedia article re blue flaming: > [@](#): > > The flammability of bodily gases has caused serious problems in the medical operating room and also in animal slaughterhouses. There have been many reports in the medical literature of “life-threatening explosions” in patients undergoing electrocautery of colon polyps or other lesions. In one case, the explosion resulted in a six-inch (15 cm) hole in the patient’s large intestine. However, the hole was repaired, and the patient recovered. :eek: Jeebus Christ. That’s just what I want to wake up in the recovery room to hear. “Now, the operation went really well. Except for the fact you now have more holes in you than you did before.” ---

Except for the fact you now have more holes in you than you did before.” Meh. I put a hole bigger than that in my girlfriend’s colon last weekend, and she’s doing just fine. Maybe even a little better, in fact. [Previous page](https://boards.straightdope.com/t/is-it-safe-to-light-a-fart-on-fire/466100.md?page=1)
