"The Sui-kin-kutsu" Japanese musical instrument

My Facebook friends from Japan explain me that this is : 1. It's a beautiful music created by water drops falling...  ...2. 徐芷婕 i've saw that in Kyoto botanic garden, as i know, it's a clay pot barried underground and water droped upon through a set of banboo pipe, makes a special sound like tiny bell from far away, pretty amazing....
