I may be wrong here, not being to educated on the matter. But I seem to remember from my boy scout days that the "pop" is created by gases being suddenly ignited from inside the cells of the wood.

Could be a number of things.
Different woods do different things , some pop , some snap , some throw sparks ........

I know when oxygen is introduced to a hot coal bed this will happen. Probably the expansion of the gasses in the coals.
Try bamboo for a more spectacular show! (Bring a fire extinguisher though, just in case). I assume its volatiles in the wood heating up till the pressure exceeds the strength of the wooden 'container'.
My son seems to think it is when a bug gets cooked. I actually think it is a moisture related issue.
I always thought it was gum/resin/pitch pockets. Moisture might do it also, if well contained, but I know that even bone-dry mulberry or pine will pop. Indeed, mulberry coals will often pop when raked.
moisture turning into gas, building up within a "pocket" and then breaking the tinsel strength of the surrounding matter and "POP"
