beardedbruce, perhaps you can explain to me how a paintball pellet that contains glass fragments could hit a wall and explode and not leave a pattern like the ones in the picture I posted in my response to Keith. Explain how glass fragments would alter the behavior of any liquid substance that is projected at high velocity in pellet form against a hard surface like a wall, impacting it, exploding, and leaving its liquid substance on the wall. How would the presence of glass fragments negate the tendency of things that hit a hard surface at high velocity to want to spread outward in a radiating pattern? Any time something that contains liquid or any other fragmentable substance hits a hard surface at high velocity, it forms a pattern that radiates away from the point of impact. Even human bodies falling from tall buildings. How would the presence of glass fragments alter this behavior?
