liquid oxygen

Liquid oxygen ( O2) (cyan 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, pale cyan liquid form of dioxygen O2. It was used as the oxidizer in the first liquid-fueled rocket invented in 1926 by Robert H. Goddard, an application which is ongoing.
