Episode 235 - Dragon Wash



The brass water basin as shown in the photo is known as the Dragon Wash.

If you rub the handles of the dragon wash for a while with wet hands, the basin will emit some distinct sound with water droplets jumping out from the water surface of the basin.  This is a resonance phenomenon.  The force transmitted through the handles drives the wall of the basin and the water to oscillate with greater amplitude at a specific frequency.

It would appear that, apart from passively waiting for / receiving live water, static water can also be awakened by actively applying suitable oscillation force.
