Have you ever filled a wine glass half full of water, wet the rim and slowly moved your fingertip around the edge? It makes the glass "sing" because of the sonic vibrations. Well that's basically the same principle with the magical ancient Chinese Dancing Water Bowl. Simply fill the bowl with water, gently rub the handles and eventually the sonic vibrations will make the bowl "sing" as well as splash the water up and down like it was dancing. Display it in your home if dry and outside if filled, for obvious reasons. Very cool.
