Liquid nitrogen, which has a boiling point of -196C, is used for a variety of things, such as a coolant for computers, in medicine to remove unwanted skin, warts and pre-cancerous cells, and in cryogenics, where scientists study the effect of very cold temperatures on materials.
It has also become increasingly common at top restaurants as a method for instantly freezing food and drinks, or creating an impressive cloud of vapour or fog when exposed to air.
The avant-garde cooking technique was arguably made famous by chef Heston Blumenthal, who put nitro-scrambled egg and bacon ice-cream and nitro-poached aperitifs on the menu at his Berkshire restaurant, The Fat Duck.
Since then a number of restaurants have started using the technique, with a cursory internet search throwing up recipes for nitro-caramel popcorn and pumpkin pie ice-cream (made with liquid nitrogen) among others.
Professor Peter Barham, from the University of Bristol's School of Physics, says liquid nitrogen is "simply the harmless gas nitrogen, which has been cooled to such a low temperature that it becomes a liquid".
But he says the liquefied gas, which is intensely cold, can cause frostbite or cryogenic burns if it is not used, and handled, properly.
For laboratory personnel in particular, there is also the risk of asphyxiation if liquid nitrogen - which is colourless, odourless and tasteless - is used or spilled in a confined space. Lab worker James Graham died from asphyxiation in 1999.
Liquid nitrogen also has a large expansion ratio on evaporation - one litre of liquid nitrogen can result in about 700 litres of gas - so only a relatively small volume of liquid nitrogen has to evaporate within a room to result in an oxygen deficient atmosphere. Pressure can build up in a sealed container due to the boil-off of nitrogen gas, so insulated vacuum-jacketed pressure containters are used to store it.
