|The creator of the video shows stone like animals called Hin Hoi, meaning rock shell fossil.
He got them from a temple near Udon Thani and was told they are to be found at a specific location along the Mekong River. |
They react by moving when you put them on a thin layer of lemon juice.
According to a French website, where you can order them, these stone-like shells are really alive, but will eventually die. Then they will not move anymore I guess, so the words rock or stone and fossil are a bit misleading.
Small Hin Hoi cost €19/$26 and bigger ones €25/$37.
