Virtually every object that you see around you has passed through the hands of a mechanical engineer. :) Trebuchet If your catapult breaks, it will probably be at this joint, so use plenty of glue and make it secure! Hang the eraser from the paper clip hook. Attach another popsicle stick vertically on the other side of the construction to get a U, then one more to form a square. Then attach a popsicle stick across the two sticks fanning out so as to join them. Make sure your trebuchet is sturdy and the frame holds together. Twist an elastic band around each end to hold them in place. If you have trouble with the trebuchet releasing the projectile at the right time, you can adjust the weight of the counterweight or remount the swing arm through a different hole. Secure it in place with rubber bands. Start with about seven popsicle sticks and place them on top of each other. (We do not recommend using glue for this stepthat way you can remove the crossbar and swap out the arm to make changes.). Slide the pencil into the milk shake straw. We hope to restring all the weights and possibly put a new nail in before doing our final test tomorrow. Comment Download Step 1: What you need: 1.
