When a 30-year-old Delhi man walked into a bar, all he wanted was a good drink, but he ended up with his stomach ‘open like a book’. What he had consumed was liquid nitrogen that has a boiling point of -195.8 degree Celsius and is used to instantly freeze food and drinks. Liquid nitrogen has an expansion ratio of 1:694 at 20 degree Celsius, meaning one litre of liquid nitrogen at 20 degree Celsius can expand to 694 litres of nitrogen gas. And, as it evaporates, liquid nitrogen freezes everything around it, including tissues that come in contact with it. By nature, liquid nitrogen expands manifolds and evaporates when left at room temperature.
