This is a indoor diving location called "Tauchcenter Nullzeit" in Duisburg Germany. If you are not afraid of cold water (11°C) you should pay a visit there. It's great fun.
Definitely REAL.. O___O (Pay no mind to the zipties holding everything in place.) You see, the human skeleton is an amazing organism.. Zip-Ties are created during the final stages of decomposition to facilitate the identification process.) 😉😋
