I would like to find out why it is that when you have a camp-fire, the wood that you burn pop's all the time? Some say it's bugs, but I think it's from gases.

Mostly it's from steam. Small pockets of moisture flash over to steam, causing sudden local expansion. The wood fibers surrounding the pocket of steam, having become brittle from the heat, can no longer contain the pressure - and you get a miniature steam explosion.

Same reason that popcorn pops. Pockets of moisture are trapped and turned to steam and finally blow out with a pop.

Green wood will pop as the fluids inside expand and explode from their vacules inside the wood.
