Drinking straw

A drinking straw or colloquially known as straw or tube due to the former, natural origin, is a tool which allows to absorb liquids to drink this.

The material previously mainly straws, is now in the disposable products mainly thin-walled plastic such as polyethylene or polypropylene. However, one can also stems from thick-walled plastic, stainless steel or unbreakable glass obtained, the latter being a greater risk of injury salvage. Straws were already used by the Sumerians. The modern drinking straw was patented in 1888 by Marvin C. Stone.

Standard forms

The disposable products are practical to obtain in every imaginable color and length as well as with different diameters. Also various ornaments, such as phosphors, can be found for the party needs. In the shaping of the imagination are almost no limits (knots, spirals, waves, etc. ). However, the mass products usually have a straight, rigid form or are in the upper part to snap off, then they are called Flexhalme.

At the bottom of the stalks are produced with either straight degree or cut at an angle, so that a tip is formed, with which one can break through at the point indicated a beverage carton.

A further possibility is emulating a spoon at the bottom end of the straw. This way you can stir both drink without having several " tools " in the glass.

Special products

The upper end may have to be a special form four holes instead of one large opening ( Sensory Straw ), bringing the drink evenly distributed in the mouth.

It also drinking straws are produced which can be telescopically extended to nearly twice the length. More of a gimmick or an eye-catching are drinking straws that are wound several times in the upper part.

Further, the blades can be fitted on the inside with vitamins and flavors; drinking these are then dissolved and added to the beverage.

In South America, yerba mate through a metal drinking tube ( bombilla ), at the bottom of a screen is attached is drunk.

Worth mentioning

There is blank thesis that will drunk faster if you drink an alcoholic beverage through a straw. For this, there are probably two reasons: First, the drink is transported through the straw in small sips through the mouth, so that a larger portion of the alcohol already in the mouth through the oral mucosa can get into the blood. On the other alcohol is degraded in the stomach by the enzyme alcohol dehydrogenase to a certain extent. For the alcohol passes through the oral mucosa directly into the bloodstream, but this degradation process can not act. A third hypothesis suggests that with increased stalk inhaled alcohol fumes and accelerated through the lungs would be included.

The maximum length that can have a straw, so you can still drink, depends on the size of the vacuum which can generate in the mouth against the environment of drinkers from.
