Liquid oxygen (O2) (light sky-blue liquid) in a beaker.When liquid oxygen (O2) is poured from a beaker into a strong magnet, the oxygen is temporarily suspended between the magnet poles, owing to its paramagnetism.
Liquid oxygen, sometimes abbreviated as LOX or LOXygen, is a clear light sky-blue liquid form of dioxygenO2. It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H. Goddard,[1] an application which has continued to the present.
