Can You Light A Fart On Fire?

Out of all the gases in our farts, hydrogen, and methane are the flammable ones. This means they can be set on fire. Even though you produce flammable gases, it isnt enough to create a flamethrower. Humans can fart anywhere between 25-100 ml at a time. Thats only enough to keep a flame going for a few seconds. If farts could burn any longer, wed probably be using them to make electricity! Of course, large quantities of it could help our energy problem if we could address the large quantity of awkwardness that would come from collecting farts on such a massive scale!
