Catapult Building 05/20/14

After a few trial runs the day before, we decided to do another one with the catapult completely done. After noticing that the dowel rod after it had been spray painted was causing trouble on the trigger, we took a clean piece and redid the trigger. We had to use a lubericant to make the friction between the dowel rod and arm decrease. After being happy with our catapult, we loaded it into the truck and took it home.
