No, I finished that project. I needed something to hold my homemade fission weapon in, not a cannon. Amos, however, stumbled against my little toy while he was carrying a load of lithium VI deuteride, and the heat from my little ol' firecracker trigger a fusion reaction in the LiD, and, well, Amos hadn't set up the takamak yet, and suddenly we had created a place called "Los Llanos Estacados." The radiation will die down to a habitable level in less than thousand or so years, so it wasn't any big deal. Besides, nobody was hurt and nobody called the cops and we also were out of town and have alibis besides.
