The casual voice of the filmmaker explains standing waves using a linked chain bordering a neighborhood parking lot, a bucket of blue-colored water, and a rope tied to a fan blade. He uses the appropriate vocabulary (frequency, wavelength, antinode, and resonance), but fails to explain all of the terms. This could be useful for simply demonstrating standing wave motion, but ideally you would have your physical scientists create them in the lab rather than just watching them online. Also, be aware that the shaky video quality and the muffled sound of wind blowing are a bit distracting.
