How herring farts almost led to a diplomatic crisis

A video from TEDx Goteborg, with this description;

How can herring farts in the Stockholm archipelago almost lead to a diplomatic crisis? Or a bra be converted into a gas mask in case of emergency? To Magnus Wahlberg this is everyday stuff, and proof that science doesn’t have to be dull to be important. He is a biologist and Scandinavian desk chief of the science humor magazine Annals of improbable Research, and has himself been awarded the Ig Nobel Prize (for those herring farts). It is an alternative Nobel Prize that honors achievements that first make people laugh, and then think.
