Airtight chamber reveals how sound disappears without air.



  • Built-in buzzer activates via external switch

  • Clear, impact-resistant acrylic construction
  • Compatible with standard hand vacuum systems


This apparatus helps students explore the fundamental role of air in sound transmission. Once sealed and evacuated, the chamber isolates the buzzer's vibrations from the surrounding environment, creating a silent visual paradox. Ideal for physics demonstrations, the setup encourages critical thinking and discussion. A vacuum pump is required for full functionality and must be sourced separately.
