====Summary====                   
{{$demo.summary}}



====Procedure====  
  - Wind or activate the music box mechanism.
  - Hold the music box in the air and listen to the faint sound produced.
  - Gently press the base of the music box against a firm bench or table surface.
  - Wind or activate the mechanism again and observe the louder, richer sound.
  - Discuss how the surface enhances the volume through vibration.

====Variations====
  * Test different surfaces (e.g., wood, metal, plastic) to compare amplification effects.
  * Try placing the music box against hollow versus solid objects to explore resonance quality.
  * Use varying pressure—light to firm—to observe how coupling strength affects sound.




====Safety Precautions====
None




====Questions to Consider====
  * Why is the music box much quieter when held in the air?
  * How does pressing it against a bench amplify the sound?
  * What physical principles (like resonance or forced vibration) are at play?
  * Which surface gave the loudest sound—and why?
