How I broke a wine glass with my VOICE (using science!)

Since science is all behind this, you can numerically and scientifically explain how you broke the glass by using a microphone and an audio analyzing software. Go to quiet place wherein no external noise like high and low pitches or whatever sound would likely interfere what you are to record. Place the microphone inside the glass (by not touching the walls with your mic) and use a recording software like windows media player etc. to record it's sound while you hit or tap the wall of the wine glass ( in a gently manner with a hard object). You will hear a tone. Get an audio spectrum analyzer software to open your recorded sound and analyze the highest frequency (in Hertzian wave unit or simply in Hz)  that appears on your recorded sound and that's it. That's the frequency you need to produce to break a wine glass. 

Here comes your part to break it without severe exhaustion. Record your voice just what you did on your this video and analyze it with an audio spectrum analyzer to see where in the spectrum you sound (in terms of frequency) most and adjust your voice to the exact resonant frequency of the glass you acquired. Do it in a repeatedly manner wherein the wine would self break based on your recorded data.
