So I've never understood what's coming out of this guys mouth. Now it's a cool shot, but what the hell's coming out of his mouth? At first, I thought they were sparks, but there's no metal on metal contact. I then figured it was saliva, but there's no way that much saliva was knocked out of his mouth. Now I know the average human being chooses not to swallow his or her saliva, and he or she will often keep it contained for hydration or until they can no longer contain it, but I find it unlikely that this is the fluid. Unless he had a mouth full of spit, that's something else. Plus it has a yellowish color.
