This was done as a engineering class project, and we had a set of rules to go by.
1. The trebuchet had to be made entirely of cardboard. For the parts that allow movement, PVC piping, string, and aluminum foil were allowed.
2. The trebuchet had to be waterproof! For this, we were allowed to do this by any means necessary, without inhibiting the function of the trebuchet.
3. The trebuchet must fit within a box with the dimensions 18in x 18in x 18in
4. The minimum distance the trebuchet must throw to is 30ft.
***AN IMPORTANT SAFETY NOTE***
While working with any tools, safety is of the utmost importance. That is why, while working on this project and any other, you must wear eye protection. You must also be sure that you keep long hair tied back and keep things off of around your neck.
Following these basic safety procedures will ensure a safe working environment while working on this project.
