Swimming Pool by Leandro Erlich is an art installation with a permanent home at the 21st Century Museum of Art of Kanzawa, Japan. It has also had temporary installations at MoMAPS1 and the Venice Biennale.
Conceived in 1999, Swimming Pool allows visitors to look down into a seemingly full pool of water with fully clothed visitors walking around the bottom of the pool. From below, the blurry vision of looking up when underwater is recreated using a thin piece of glass with water running over top of it.
Complete with a climbing ladder, swimming pool is a fun and interactive installation that creates the illusion of being underwater whilst remaining completely dry.
