Indie Lab - Beautiful String-Coupled Pendulum Oscillator Analyzed

This student designed, built, and analyzed a pendulum system that shows the transfer of energy from one resonator to another. Incidentally, Huygens also noted that two pendulum clocks on a wall eventually reach anti-synchronization, which you'll see later in her demonstration. Here's a question for ya: can you find three distinct ways to explain why the student's favorite graph has the shape it does? Go.
