Suikin Kutsu is a device that is located in Japanese garden. If water comes into it, it makes sound. The purpose of this project is to build Suikin Kutsu myself.

Pot that has a whole in bottom is used. The pot is buried into the ground with upside down. Put water into it makes beautiful sound because water hit the water on bottom of the bottle. Some water is needed on bottom of the bottle to make sound. If you bury the pot as usual, it does not hold water properly, maybe too much or too small. To hold proper amount of water, very careful mixture of sand and stone is needed.
