Avoid cannonballing into this pool. What you're looking at is actually an art installation by Argentinian artist Leandro Erlich. Found in Japan's 21st Century Museum of Contemporary Art, the swimming pool installation gives onlookers from above the illusion of people performing land-based activities in the bottom of a swimming pool.
The fake swimming pool is created using a sheet of glass with a layer of water that's only 10 centimeters deep. Underneath the pool is an aquamarine chamber where visitors can experience underwater submersion without having to get wet. But the main draw to the chamber is the fact that you can freak out spectators above you as you move through water as easily as you do through air.
What activities will you perform in the fake swimming pool?
