The ice block expedition of 1959 (Norwegian: isblokkekspedisjonen) was a publicity stunt carried out by the Norwegian insulation material producer Glassvatt. Responding to a challenge from the radio station Radio Luxembourg, Glassvatt decided to equip a truck to bring a three-ton block of ice from Mo i Rana by the Arctic Circle, to Libreville by the Equator. There was no form of refrigeration applied, and the expedition was intended to display the efficiency of the insulating glass wool used. The truck also brought 300 kg of medicines to the hospital of Albert Schweitzer in Lambaréné.
