Temperature in a body, is also a clock.

When water freezes, does time stop ticking?

Looking at the bubbles frozen between layers of ice reminded one of the fragility of life that fluctuates as the temperature changes. Rising temperature melt the water body in all vessels. As an ice melts, the bubbles that broke free from entrapment of the water also releases gas and entrapped micro-species.

This relationship between liquidity of time amidst the fluctuating temperature is meant to be reminded through the tiniest sound of one droplet hitting the water surface in Susurance. The glass ice counter is deisnged with references to Clepsydra an ancient method of measuring time with water and Suikinkutsu, the Japanese water harp. The structure supports amplification of the sound of each melted ice droplet hitting the surface below.
