We went to a local Pumpkin Chunkin' team demo today. Their motto was "I do dumb things". It was the first time they were trying out a new design for their machine, and they were still trying to work the kinks out. They managed to get one launch off, but they ultimately broke the arm on the machine on the 2nd run, when they were trying to find out how much tension the machine could handle.
We got some can coozies, and a couple of 2 dollar pulled pork sandwiches, and watched them work on this contraption. Warning, a lot of pictures below:
