How high do you have to be to break glass?

You don't necessarily have to go so high to break a glass, rather it is hitting the exact same frequency of vibration that the glass has. So you would tap the glass to determine the frequency (you need someone with perfect pitch or an analyzer), and then you just have to hit that same note at the right intensity to break the glass.
