Nothing really went well for us. The trebuchet should have worked, but I honestly don't know why it did not. The only good thing that came from this was the experience of making something from scratch. Some recommendations for future trebuchet makers is to make sure your pouch works. This is one of the most important parts of the trebuchet. Everything else worked perfectly in my eyes. This was a fun and challenging project. Took a lot of time and work to put this together so make sure you don't leave this to the last day or two.
