Fire Breath
One of the
greatest iconic pictures of dragons is of the dragon belching fire at a
knight, but many issues exist with this scenario.
One common answer to how dragons breath fire is the thought that they
chewed on platinum and then mixed it with hydrogen (which acts as a
catalyst) and thereby produces combustion.
Here
is a link to a video simulating certain parameters to explain if
dragons lived how they would have done what they are idolized for.
