"Towards the end of my research I searched the web using the mineral's chemical formula - sodium lithium boron silicate hydroxide - and was amazed to discover that same scientific name, written on a case of rock containing kryptonite stolen by Lex Luther from a museum in the film Superman Returns.
"The new mineral does not contain fluorine (which it does in the film) and is white rather than green but, in all other respects, the chemistry matches that for the rock containing kryptonite."
Dus de schijver van superman omschreef kryptonite als sodium lithium boron silicate hydroxide (fluorine) en dat is toevallig ook iets dat bestaat. Geinig.
