Surgeons remove teen's stomach after she drinks liquid nitrogen cocktail

Professor of food physics at Leeds University Malcolm Povey said liquid nitrogen should not be consumed while still liquid, as it turns into a gas inside the body and causes the stomach to swell and burst.

"The liquid nitrogen would rapidly change into gas and blow the stomach up like a balloon...the idea that people put this stuff in drinks is just unbelievable," Povey told Reuters.

The bar which served the drink has stopped selling all liquid nitrogen drinks, said police, who are investigating the incident.
