Cadbury human cannon We hired a classic "Peterbilt" prime mover that the cannon was fixed to.(the green changed to purple in post) A metal frame was bolted to the inside of the cannon and attached to the truck. We suspended the cannon off a chain block and lowered it onto the truck. The owner of the truck thought that the cannon would look great in his front paddock. So he carted it away on his trailor when we had finished.
