How do dragons breath fire?
There are many theories, scientifically being flint in a pouch in their mouths that roll and spark, creating fire. Here’s a theory that I value highly: We eat our body by digesting it created methane, CH4, however dragons store the gas in a ‘lung’ and that serves as a bag for it, then it’s mixed with a small amount of phosphor, P4. That’s got the stuff to ignite in fire at the contact of air, so when the dragon wants to breathe fire, the methane goes into the lung and then, when the gas is in the air, the phosphor ignites and puts the methane in fire. Confusing enough?!? But it’s sensible.
