Bang takes out quarter and pounds on it with hammer on concrete step .....the concrete cracked but not the coin. My dad was pretty mad and a quarter in those days was a weeks allowance. Bang takes a quarter and sticks it half way into vice on bench bolted to floor...... took a sharp wack at it with a hammer and woweeeeeeeeeeeeeeeeee! It broke in half. I did this when I was a kid. Bang takes a dollar bill and wraps it around a minie ball ....stuffs it in a 50 calliber blackpowder rifle. Found pieces of it all over firing range.
