Sterno ("canned heat") is a fuel made from denatured and jellied alcohol. It is designed to be burned directly from its can. Its primary uses are in the food service industry for buffet heating and in the home for fondue and as a chafing fuel for heating chafing dishes. Other uses are for camp stoves and as an emergency heat source (deer-blind). It is also a popular fuel for use with toy and model steam and other external combustion engines. Sterno cans were sometimes taken on trips and used to heat pressing and curling irons and hot combs, for hairstyling, when travelers were staying at hotels and not located near salons which offered certain services that required these styling tools.

The Sterno brand and trademark is owned by the Sterno Group LLC, a subsidiary of Candle Lamp Company LLC, a portfolio company of Westar Capital LLC. The brand was purchased from Blyth, Inc. in late 2012. Blyth had acquired the business from Colgate-Palmolive in 1997.
The name comes from that of the original manufacturer, S. Sternau & Co. of Brooklyn, New York, a maker of chafing dishes, coffee percolators and other similar appliances since 1893. It had previously applied the name to its "Sterno-Inferno" alcohol burner. In 1918, it promoted its Sterno Stove as being a perfect gift for a soldier going overseas. In his book With the Old Breed, E. B. Sledge describes its use on the battlefields of the Pacific Theatre in 1944 and 1945.
Invented around 1900, Sterno is made from ethanol, methanol, water and an amphoteric oxide gelling agent, plus a dye that gives it a characteristic pink color. The methanol is added to denature the product, which is intended to make it too toxic for consumption. Designed to be odorless, a 7 oz (198 g) can will burn for up to two hours. It was discovered while producing nitrocellulose during the manufacturing process.
Nitrocellulose is a material used in manufacturing explosives and is made by combining shredded wood pulp and adding a nitric sulfuric acid mix. A by-product of the manufacturing process produces a gel-like substance later refined as Sterno.
In 2007, two NASCAR crew chiefs were fined $100,000 for lining their fuel tanks and intake valves with Sterno. When the highly regulated NASCAR fuel was added, the Sterno would liquefy, giving the car an added octane boost.
As a drink
There are many instances of people drinking Sterno to become intoxicated. Since the alcohol it contains is denatured, Sterno is poisonous. Bluesman Tommy Johnson alludes to the practice in his song Canned Heat Blues recorded in 1928.
The practice is said to have become popular during Prohibition and during the Great Depression in hobo camps, or "jungles", when the Sterno would be squeezed through cheesecloth or a sock and the resulting liquid mixed with fruit juice to make "jungle juice," "sock wine," or "squeeze".
In an article for the Journal of the American Medical Association in 1961, Capt. James H. Shinaberger, MC, writes about a study of three people who had suffered methanol poisoning as a result of drinking Sterno. One of the patients "had been drinking Sterno for about a week and had been in the city prison for 48 hours when severe abdominal pain and vomiting occurred".
In Michael Crichton's 1969 novel The Andromeda Strain and the 1971 movie and 2008 mini-series based on it, one of the survivors of the deadly extraterrestrial virus is an old man who utilizes "squeeze" along with aspirin to alleviate the pain caused by a bleeding ulcer diagnosed two years prior to the "Piedmont Incident". Constant consumption of Sterno has altered his blood pH, making him at least temporarily immune to the disease. The movie also suggests "red-eye" and "pink lady" as synonyms to "squeeze".

[...] inspectors found a gel-like coating inside the manifold. Several engine builders from other teams said the substance appeared to be Sterno, a bluish gel that could provide a hotter, cleaner burn inside the engine to create more horsepower.
