Update: A representative for Syddansk University has issued a revised estimate of the compound's efficiency. They told Vice in a statement: "I am just updating our story on our website, because it turns out that Prf McKenzie made a calculation error. Pls note that it is not a SPOONFUL of this stuff, that we need to rid a room of oxygen. It is a bucket (10 litres). We apologize."
Well at least they admitted it was all hype.
