double pendulum

thingiverse

I mounted a double pendulum on a 4 ft diameter circle of plywood that shone brightly with glow-in-the-dark paint. The pendulum's short arm holds a UV laser pointer that traces the intricate path it takes across the glowing surface, creating an mesmerizing display. The pendulum itself has a radius of 2 ft, making its motion visible and easy to follow. I designed this setup to showcase the beauty of physics in action. It's great to see my project come together - this double pendulum is actually what inspired me to join Thingiverse in the first place!
