Floating is the relaxation practice of being buoyant in approximately 10 inches of water in a solution of 1,000 pounds of magnesium sulfate, otherwise known as Epsom Salts. Floats last no more than 60 minutes. The temperature of the water is set to the body's normal skin temperature.  This practice can be accomplished in a special floatation device like a float pod, a floatation tank or a float room.  Some may have heard of a sensory deprivation tank, this is the same type of device as mentioned above.
