Mr. Iddings' afternoon AP Physics I class finished their fully functioning trebuchet project. Caleb McMullen and Mr. Bryan Iddings load the trebuchet with a mini pumpkin only seconds before launch. Other Physics students Andrew Merritt, Harrison Richter and Jenny Im are present off camera.  The trebuchet is a type of French medieval catapult, typically used  in fortress sieges. This example specializes in launching gourds.
