Strohhalmen

Strohhalmen, German for drinking straws, are typically hollow tubes used to transfer liquid from a container to a person's mouth. Historically, these were made from natural materials such as straw, reeds, or hollow grasses, which is where the name originates. Early documented use of drinking straws dates back to ancient Sumeria, where they were likely used to filter out beer sediment.

In modern times, straws are predominantly manufactured from plastic, paper, or metal. Plastic straws, due to their durability and low cost, became the most common. However, growing environmental concerns about plastic waste have led to increased use of biodegradable or reusable alternatives. Paper straws, while compostable, can sometimes disintegrate quickly in liquids. Metal straws, often made from stainless steel, are durable and reusable, but require cleaning. Bamboo and glass straws are also available as eco-friendly options.

The design of a straw is generally a simple cylinder with an opening at both ends. Some straws are flexible, featuring a corrugated section that allows them to be bent, facilitating easier drinking. The diameter of straws can vary, with wider versions sometimes called "bubble tea straws" designed for thicker beverages. Their primary function remains consistent: to aid in the consumption of liquids, particularly from cups or glasses.
