Can someone please explain to me about the thing with the water bottle?

How does that work? :o

Basically, he measures the amount of water that drips into the bottle during the time that sung ho is out. So that in the future when sung ho goes out again, he could do the same thing again to estimate when sung ho would return as he went about doing what he needed to.

it works like an hour glass except that instead of sand, he used water and the cells on the bottle to determined the passage of time.

One of the first timer was created by a roman prostitute in a similar way. She would time her session with her clients using a large bowl and smaller bowl . A small hold was drilled at the bottom of the smaller bowl. The large bowl was filled with water and the smaller bowl then placed in the water. Once the smaller bowl was filled with water, it would sink to the bottom making a sound alerting that the time with the current client was up.

that`s..interesting
