Bob, what the heck was that? Is there something that shoots an anvil?
" Anvil shooting involves placing one large blacksmith anvil upside down on the ground and filling its cavity with a fine grade of black powder. A second anvil weighing up to 150 pounds is then placed upright on top of the bottom one. The powder is ignited and the top anvil is thrust as high as 125 feet into the air. The earth literally shakes; and the deafening boom, it is said, can be heard from as far away as 15 miles. It often is catapulted higher than the tallest trees."
