Why do sonic waves go boom? How can sound shatter a glass?

Can you explain these phenomena?
    and more neat demos of resonance (or beat frequencies?)



This video gives some good info about sonic booms, (but they misspelled Propagate, sigh)

For you future theoretical physicists, here's a neat simulation that shows how wave phenomena can explain orbital levels of electrons (remember that 1s2, 2p6,2p2 stuph?)

And one more cool example of a shock wave/sonic boom from a rocket passing Mach 1
