Physics question

Check this out:

If you can't see, the water boiling on the stove is somehow making the pot vibrate on the burner. What's causing it?

My hypothesis is that the burner and pot make for a barely-balanced system that can rock back and forth just a bit, and the bubbles coming up are prodding it such that it gets a harmonic oscillation going. Thoughts?
