Bill Marecak of Pembroke is a retired science teacher who loves going to his cottage on beautiful Lake Dore. Bill has designed and constructed an ancient trebuchet that is set up on the front lawn of his property. Bill and his friends get together to launch bowling balls and other assorted objects into the water. They fire with remarkable precision at various targets. Everything is retrieved from the lake, and then they do it all over again. It's all in the name of science and fun.
