When a loud sound hits a glass, it makes the glass vibrate, like when you tap a spoon on a bowl and it hums. If the vibrations get too strong, the glass can't hold up anymore and it breaks! Imagine the glass is dancing really fast until it falls apart.
Examples
- A singer breaks a wine glass by singing just the right note.
- A loudspeaker near a glass makes it vibrate and eventually shatter.
- When you shout in a quiet room, sometimes your voice can make a glass shake.
