This is a cival war "reenacter" if you will. This man and his group of guys
who reenact the Civil War visited the Sam Houston history department. During the
"gun safety" part, he demonstrates what would happen if you fired the gun without
a live round. Just the amount of air that is expelled can do damage. His target
was a plastic water bottle and you can tell by the water droplets in the air that it
exploded. I gave it a sepia tone so it would look more "authentic."
