It is pitch black in the depths of the sea. The silence is only broken by the muffled sounds of the sea creatures. Blue fish, giant jellyfish and bizarre creatures float in this weightless atmosphere. With Jim Curious, the little diver, you explore the bottom of the ocean: here you can see mysteriously waving algae and the remains of a galleon, there the outline of a sunken city and ... Help! A giant shark! Visitors of all ages can literally immerse themselves in a magical underwater world with just black light, 3D glasses and stereoscopes.
