According to my Radio Shack SPL meter, I can hit at least 127 decibels — which is where the meter tops out.
Now, I have not yet replicated that process in a more controlled test, in a suitably calibrated environment. But I would be interested to do so.

- gozur88 9y agoEh... isn't the secret of the trick to be at the resonant frequency? To brute force it seems like a superhuman feat.
- jaredandrews 9y agoFrom the article: > "Even if you could excite the cup, that doesn't guarantee it would break. Fracture depends on the size of the initial defects." I have to wonder if Jaime tapping the glass with a spoon in that video not only reveals the frequency he needs, but more crucially introduces tiny fractures.
