I recently discovered bells such as the Liberty Bell and most major bells in 1700's were made out of horse poo and the process is still used today!!
"Rotating the template as a guide, layers of a clay mixture were applied to the brick oven until it was smooth and formed the shape of the inside of the bell. The clay mixture contained horse manure, horse hair, and hemp to increase its strength. The core was dried by placing hot coals in the oven."
Maybe we should be making cars out of it and call them poomobiles?
