the Bear SG there is a room, with probably an acrylic or something ceiling.. then there's a swimming pool
pokkagreentea SG oh yes, this swimming pool is totally dry inside. No water. But on the surface, it looks like an ordinary swimming pool with water. I'm not sure how to get in/out of the pool though.
maurizio13 SG At first sight, I thought it was a room with a ceiling with water above. But there's a girl climbing up the ladder, looks as if he/she is about to reach the top of the pool with another person extending hand to help.
aiglosicicle SG my guess is there is door in the pool for people to go in just that it is coloured blue and cant be seen. between the hole which is the pool and the outside, there is a panel of glass with flowing water on top. that creates the whole effect without drowning the people inside
