I was thinking about how fire guns are very loud and how its worst in close environments (I had never shot a gun cuz im not american) and I remembered the Mirror room scene in John Wick Chapter 2.
I was thinking if by shooting once, many mirror could break because of the sounds of a gun alone. Has someone tried this or see it happen?
Unless you had a muzzle that specifically created resonanting waves at the glasses harmonic frequency, and a bunch of glass with the same resonance would all shatter even with a sound wave as small as a voice (much less a gunshot)
