How to Make a DIY Catapult with Popsicle Sticks

TL;DR

To make a DIY catapult using popsicle sticks, stack five craft sticks and secure them with rubber bands. Attach a water bottle cap to a single stick, create a V-shape with another stick, and assemble the parts to launch small projectiles like pom poms or marshmallows, demonstrating the physics of stored energy.
