Bottles have one commonly known form of acoustic resonance, but double-walled bottles have a second, and exploring their interactions can teach students about vibrations and oscillations.

Using concepts students are already familiar with — like how bottles vibrate — can serve as a helpful anchor for more complex topics.

Physicists at NYU have discovered a new type of time crystal—an exotic state of matter whose particles rhythmically “tick” while levitating on sound waves.
