1. What I think will happen when the sound is played for the wine glass is it will break and shatter at the right resonance.
2. What really happened was it did not shatter but I saw it shake a little bit.
3. What does resonance have to do with bridge building?- because if you get the right residence or you don't build it right than the bridge will crumble.
