Question

Sabotage is French. What did the saboteurs use?

Answer 1

The Norwegian heavy water sabotage (Bokmål: Tungtvannsaksjonen, Nynorsk: Tungtvassaksjonen) was a series of operations undertaken by Norwegian saboteurs during World War II to prevent the German nuclear weapon project from acquiring heavy water (deuterium oxide), which could have been used by the Germans to produce nuclear weapons.
