Waterbed simulates weightlessness

Researchers at King’s College London, UK employing a novel simulation of microgravity: adding magnesium salts to a half-filled waterbed. They were inspired by the Dead Sea, where swimmers float on the surface because of the high salt content. This Hyper Buoyant Facility is used to test a new Skinsuit design, which adds gravity-like loading to the bodies of astronauts in orbit.
