Stirling Warwolf Trebuchet
Even though it's scaled to 1/20th of its original size, this historically accurate replica of Edward the First's response to the 1304 siege on his Stirling Castle could still probably catapult most of your neighbors' free-roaming yellow lab shit back into their yard in a few, diligently-compacted loads. Dubbed the "Warwolf", the trebuchet stands 18 inches tall at its peak, and has an arm capable of setting its projectiles a-sail up to 60 feet. The DIY kit includes over 140 pieces, projectiles scaled to represent 100- and 350-pound missiles, plus two medieval warrior figurines on whom to place the blame should the contraption misfire, hit an unintended target, or otherwise compel you to call your attorney. The manufacturer claims assembly instructions are very thorough, and provide step-by-step support with diagrams, photos, and tuning tips, making the model "a joy to build." However, we find this very hard to believe, given that 140 pieces is about 135 pieces south of our perceived realm of "joy". Some additional tools are also required, such as glue, flat and 1/4-inch round files, clamps or rubber bands, scissors, and sandpaper.
