We encourage protective eyewear for this challenge! You must create a catapult using any materials you have on hand. Commonly used items include popsicle sticks, rubber bands, pencils, bottle caps, binder clips, and more. We are looking for distance more than height for your projectile. The projectile can only be cotton or paper btw.. good luck figuring out how to launch those very far...muahahaha (that's an onomatopoeia!)
