Norwegian heavy water sabotage happened in 1940.
The Norwegian heavy water sabotage was a series of operations undertaken by Norwegian saboteurs during World War II to prevent the German nuclear weapon project from acquiring heavy water, a critical component for producing nuclear weapons. The saboteurs successfully destroyed German heavy water production facilities multiple times, impeding the progress of Nazi Germany's nuclear program.
heavy water
The German ship that was sunk carrying heavy water was the SS Hydro, also known as the SF Hydro. It was sunk by a Norwegian saboteur team during World War II in order to prevent the Germans from acquiring the heavy water to use in their nuclear weapons program.
Heavy water occurs naturally in all water in a proportion of about one part in twenty million. In order to get a certain amount of heavcy water you have to isolate the heavy molecules out of a large quantity of water. The Germans used fresh water because there would have been no point in having to desalinize before they could even begin isolating the heavy water from the regular water. Heavy water is heavy because one of the hydrogen atoms in the water molecule has a neutron in its nucleus along with the proton.

vann/vatn
It depends how heavy you are If you are heavy, it might sink or flip, If you are smaller it will just go under water when you jump
The ship was sailing in the blue waters, so far nothing had happened. But suddenly ship was sabotaged. who might sabotage a ship this big?
vann = water vannflaske = waterbotle
Nazi Germany began its 'heavy water' experiments (or, more precisely, production) in mid-1940 after its invasion and conquest of Norway, which was at the time the world's only source of this key ingredient for the production of a nuclear weapon. Production at this facility ceased several years later as a result of several Allied bombing raids and the subsequent attempted transfer to Germany of the heavy-water supply, which was lost in yet another Allied-inspired sabotage operation.
The North Sea, the Norwegian Sea, the Barents Sea.
So you take some water...a lot of it. Then you have heavy water.
