'The Swimming Pool' by Argentinian artist Leandro Erlich

he created this fake pool or The 21st Century Museum of Contemporary Art in Kanazawa, Japan.

Leandro put two clear acrylic glasses about a foot apart and filled the space in between with water. The top surface is also filled with about 4 to 5 inches of water so that it looks like a realistic pool. Watch the video, its so cool!
