Sound can do some weird things when things which most of us don't see, the main example being the waves of vibration which flow through the air. But when sound is powerful enough and close enough to a physical object we can sometimes see those vibrations shaking the object. But if you were to get a really low frequency and put it up against water? That's exactly what happens here and it's truly astonishing. It literally changes the way you view water. Instead of it just flowing like usual, it looks like it's floating almost at really unusual angles.
