The Float Studio, Ocean Township

People who aren't astronauts can still escape gravity. All it takes is a stint in a float tank at the The Float Studio, which is conveniently still located on Planet Earth. The water inside these tanks is ultra-buoyant, thanks to the sheer quantity of epsom salt dissolved in each one: 900 pounds in 10 inches of water, to be exact.

The perfect experience in the tanks doesn't just simulate a trip to outer space, though. It also has myriad health benefits for the body and mind. Relaxing in a float tank—also known as a sensory deprivation tank— can improve sleep patterns, relieve pain, and even improve concentration.
