Use one hand to pull down on the eraser. A toy trebuchet might seem harmless, but even a small projectile can cause eye damage. Reply A trebuchet relies on gravitational potential energythe type of energy you get by raising something up off the ground. We hope to restring all the weights and possibly put a new nail in before doing our final test tomorrow. How does that work? You'll need to wrap the rubber band around several times to make it nice and secure. Welcome to Storm the Castle! Popsicle Stick Crafts.
