The material which Volvos are made of. It's one of the strongest known materials on earth.
An 18 wheeler swerved on the wrong side of the highway, causing a head on collision with a Volvo. The driver of the 18 wheeler died, but the people inside the Volvo were safe because of their Volvonium shield.
The hardest metal known to man, which Volvos are made of.
Volvos are actually harder than diamonds.
They're made out of a material called
Volvonium, mined in the mountains of Sweden by
hard-working Nordic Gnomes. After the material
is melted by launching it into the sun via
herring-powered rocket, the molten Volvonium is
allowed to cool slightly, and is then beaten
into shape by Mjolnir, the hammer of Thor.
