A drinking straw or drinking tube is a small pipe that allows its user to more conveniently consume a beverage. A thin tube of paper, plastic (such as polypropylene and polystyrene), or other material is used by placing one end in the mouth and the other in the beverage. A combination of muscular action of the tongue and cheeks reduces air pressure in the mouth and above the liquid in the straw, whereupon atmospheric pressure forces the beverage through the straw. Drinking straws can be straight or have an angle-adjustable bellows segment.
Plastic straws account for a significant amount of unrecycled plastic waste, and contribute to plastic pollution in the ocean. As a result, numerous campaigns in the 2010s have led to companies considering a switch to paper straws.

History
The first known straws were made by the Sumerians, and were used for drinking beer, probably to avoid the solid byproducts of fermentation that sink to the bottom. The oldest drinking straw in existence, found in a Sumerian tomb dated 3,000 B.C.E., was a gold tube inlaid with the precious blue stone lapis lazuli. Argentines and their neighbors have, for several hundred years, used (for drinking mate tea) a similar metallic device called a bombilla, that acts as both a straw and a sieve.
Rye grass straw
In the 1800s, the rye grass straw came into fashion because it was cheap and soft, but it had an unfortunate tendency to turn to mush in liquid.
Wax paper straw
Marvin C. Stone patented the modern drinking straw, made of paper, in 1888, to address the shortcomings of the rye grass straw. He came upon the idea while drinking a mint julep on a hot day in Washington, D.C.; the taste of the rye was mixing with the drink and giving it a grassy taste, which he found unsatisfactory. He wound paper around a pencil to make a thin tube, slid out the pencil from one end, and applied glue between the strips. He later refined it by building a machine that would coat the outside of the paper with wax to hold it together, so the glue wouldn't dissolve in bourbon.
Early paper straws had a narrow bore similar to that of the grass stems then in common use. It was common to use two of them, to reduce the effort needed to take each sip. (The cocktail straw, which is sometimes used in pairs, may be derived from such early straws.) Modern plastic straws are made with a larger bore, and only one is needed for ease of drinking.

Types
- A basic drinking straw is straight for its full length.
- A bendable straw or "bendy straw" (known in the industry as an "articulated straw") has a concertina-type hinge near the top for convenience. This variation was invented by Joseph Friedman in 1937.
- Candy straws, such as licorice straws (or lico-straws), are made from some type of chewy candy.
- cereal straws are made by Kellogg's.
- "color-changer" straws change color when cold (or hot) liquid passes through them. At some restaurants, frozen beverages like slush or frappes are served with color changing straws. Many of these are larger in diameter than typical straws to aid in drinking the thicker beverages.
- A "crazy (or "krazy") straw" is hard, transparent or translucent plastic and has a number of twists and turns at the top. When liquid is sucked through the straw, it quickly flows through the winding path, creating a mildly amusing spectacle, popular with children. The crazy straw may have some therapeutic benefit for people with autism.
- Extendo-straws come in small plastic wrappings like miniature straws, but can extend to reach the bottom of the carton.
- Flavor straws are a form of drinking straw with a flavoring included, designed to make drinking milk more pleasant for children. They were first marketed in the United States in 1956 as Flav-R-Straws. In recent years, newer variations of the original idea have been resurrected in forms such as Sipahhs, and Magic Milk Straws that contain hundreds of flavored pellets encased within a stiff plastic straw.
- A miniature straw is often attached to a drink box.
- "Sanitary" straws are individually wrapped to avoid contamination. Straws were originally marketed as a means for people to reduce the risk of contracting an illness from improperly washed containers, glasses, or cups.
- A spoon straw features a cut-away shape at one end that functions as a miniature spoon. It is intended for slush drinks and milkshakes. Their original purpose was to avoid ice clogging up the submerged end of the straw.
- A wide straw is used for sipping bubble tea. The larger diameter is necessary to accommodate the drink's characteristic tapioca pearls, and can also be used for stirring. The tip of these straws are sometimes cut at an angle creating a point. This allows the straw to puncture the plastic cover of the cup. Wider than normal straws are said to give a better taste. McDonald's says they use wider straws "so all that Coke taste can hit all your taste buds".
Materials
- Polystyrene straws
- Polypropylene is becoming favored over polystyrene for manufacturing plastic drinking straws as polystyrene is brittle and tends to crack easily. Polystyrene is also denser than water, causing straws to sink when placed into beverages. Polypropylene straws, by contrast, are much more durable and do not sink.
- Silicone is a newer material used in drinking straws. Silicone straws are marketed for their freezability, invulnerability to cracking or peeling, and insulation for hot and cold drinks.
- Metal straws, popular among campers, are made from stainless steel, aluminum, and even titanium - carry-cases with straw cleaning-brushes are available
- Paper has been used and is used more frequently, as unrecycled plastic waste from straws has been seen to be a problem.
- Polylactic acid (PLA), a biodegradable plastic, require 68% fewer fossil fuel resources to produce than plastic and are compostable but require very specific conditions to break down fully
Environmental impact
Plastic drinking straw production contributes to petroleum consumption, and the used straws become part of global plastic pollution when discarded, most after a single use. One anti-straw advocacy group has estimated that about 500 million straws are used daily in the United States alone - an average 1.6 straws per capita per day. This statistic has been criticized as unreliable, because it is a guess made by Milo Cress, who was 9 years old at the time, after some phone conversations with straw manufacturers. This figure has been widely cited by major news organizations. In 2017 the market research firm Fredonia Group estimated the number to be 390 million.
Straws are typically made from polypropylene, mixed with colorants and plasticizers, and do not biodegrade in the environment. Since the material is strong it can however be reused or recycled into other products. Waste straws in Uganda are collected from beer and soft drink depots, cleaned, and woven into mats for picnics and prayers or joined to form bags.
Environmentally more friendly alternatives to plastic straws, some even reusable, exist, although not always readily available:
- Bamboo straws
- Glass straws
- Metal straws
- Stainless Steel Straws - cases with straw cleaning-brushes are available
- Straw straws
- Paper straws
- Pasta straws
Environmental groups have encouraged consumers to object to "forced" inclusion of plastic straws with food service. Campaigns advocate providing a non-plastic straw to consumers who request one, especially as some people have disabilities that prevent sipping from the rim. Pro-environment critics say that plastic straw bans are insufficient to address the issue of plastic waste, as mostly symbolic. People with disabilities worry that banning plastic straws will make less accessible and many argue that alternatives to plastic straws (metal, paper, glass etc.) aren't good enough alternatives to plastics as they can be choking hazards, have allergy risks and be inflexible.
The movement follows the discovery of plastic particles in oceanic garbage patches and larger plastic waste-reduction efforts that focused on banning plastic bags in some jurisdictions. It has been speeded by viral videos, including one featuring a sea turtle bleeding as a plastic straw is removed from its nostril.
Plastic straw bans and proposals
Canada
After the British proposition, fellow Commonwealth nation Canada was considering banning the straws too. An unofficial online survey showed that over 70% of voters agreed with a plastic straw ban.
Starting in 2019, a ban of plastic straws will go into effect in the City of Vancouver, due to a vote in May 2018 that included banning other single-use items.
European Union
In May 2018, the European Union proposed a ban on single-use plastics including straws, cotton buds, cutlery, balloon sticks and drink stirrers.
United Kingdom
On April 19, 2018, ahead of Earth Day, a proposal to phase out single-use plastics was announced during the meeting of the Commonwealth Heads of Government. This will include plastic drinking straws, which cannot be recycled and contribute to ocean deterioration, damaging ecosystems and wildlife. It is estimated that as of 2018, about 23 million straws are used and discarded daily in the UK.
A few months before, Queen Elizabeth II banned the plastic straws and other one-use plastic items from her palaces.
United States
In 2015, Williamstown, Massachusetts banned straws that are not recyclable or compostable as part of its polystyrene regulations. Concord joined them the next year with a similar ban that went into effect on January 1, 2017.
On November 7, 2017, the city of Santa Cruz, California implemented a ban on all non-recyclable to-go containers, straws, and lids but allowed for 6 months for all businesses to come into compliance before enforcement would occur. On January 1, 2018, the city of Alameda, California citing the Santa Cruz effort, implemented an immediate ban on all straws, except if first requested by a customer first, and gave business until July 1, 2018 when it would be required that all straws to be of compostable paper and that all other to-go containers be recyclable.
In the first half of 2018, three towns in Massachusetts banned petrochemical plastic straws directly in the case of Provincetown, and as part of broader sustainable food packaging laws in Andover and Brookline. The city of Seattle implemented a ban on non-compostable disposable straws on July 1, 2018.
Drinking straw bans have been proposed in California (state-wide) and New York City since May 2018. Local regulations have also been passed in Malibu, California; Davis, California; San Luis Obispo, California; Miami Beach, Florida; and Fort Myers, Florida.
Voluntary conversions
After consideration of a ban in the UK, in 2018, after a two month trial of paper straws at a number of outlets in the UK, McDonald's announced they would be switching to paper straws for all locations in the United Kingdom and Ireland. and testing the switch in U.S. locations in June 2018.
A month after the Vancouver ban passed (but before it took effect) Canada's second-largest fast food chain, A&W announced they would have plastic straws fully phased out by January 2019 in all of their locations.
Various independent restaurants have also stopped using plastic straws.
Starbucks announced conversion by 2020 to no-straw lids for all cold drinks except for frappucinos, which will be served with straws made from paper or other sustainable materials.
Hyatt Hotels announced straws would be provided by request only, starting September 1, 2018. Royal Caribbean plans to offer only paper straws on request by 2019, and IKEA said it would eliminate all single-use plastic items by 2020. Other conversions include Waitrose, London City Airport, and Burger King UK stores starting September 2018. A few other cruise lines, air lines, beverage companies, and hotels, have also made partial or complete reductions, but most companies in those industries have not, as of May 2018.
Fiction
Nicholson Baker's novel, The Mezzanine (1988), includes a detailed discussion of various types of drinking straws experienced by the narrator and their relative merits.
