Cocktail shaker
A cocktail shaker is a device used to mix beverages (usually alcoholic) by shaking. When ice is put in the shaker this allows for a quicker cooling of the drink before serving. Usage. A shaken cocktail is made by putting the desired ingredients (typically liquor, fruit juices, syrups, liqueurs and ice cubes) in the cocktail shaker. Then it is shaken vigorously for around 10 to 18 seconds, depending upon the size and temperature of the ice. Varieties. There are at least three varieties of cocktail shaker: History. The cocktail shaker can be traced to 7000 BCE in prehispanic  Mexico and South America, where the jar gourd was used as a closed container. In 1520, Cortés wrote to King Charles V of Spain of a drink made from cacao, served to Montezuma with much reverence, frothy and foaming from a golden cylinder. Egyptians as long ago as 3500 BCE added spices to their fermented grain concoctions before serving to make them more palatable. By the mid-19th century, the cocktail shaker as we now know it was in wide use, invented by an innkeeper who, while using two containers to pour drinks back and forth between, noticed that one container 's mouth was smaller than the other's and held the two together and shook them "for a bit of a show". Rapid design advancement occurred during the late 19th century, with several patent improvements occurring during the 1870s and 1880s (see Patent history below), including the addition of integral strainer mechanisms to shakers. During the 1920s prohibition era in the United States, cocktail shakers were produced in many different shapes and designs, including shakers that looked like penguins, zeppelins, lighthouses and airplanes. Cocktail shaker skills and drink rituals became as important in the Jazz Age lifestyle as knowing the  latest dance step. It was after prohibition however, that cocktail shakers really reached their zenith of popularity. They appeared in movies, and were associated with the glamorous lives of movie stars. Cocktail shakers became de rigueur symbols of sophistication and symbols of the good life. In 1941, the era of the cocktail shaker faltered seriously, as the United States entered World War II and all non-essential uses of metal were redirected towards the war effort. The same companies and equipment formerly used to manufacture cocktail shakers were used to make artillery shells and other war materials. In the early  1950s cocktail shakers enjoyed a brief resurgence as soldiers familiar with them returned and became part of the housing boom featuring "rec rooms" with bars. By the later part of the decade though, shakers were quickly giving way to modern electric appliances that either added a mixing unit to the shaker's lid or did away with the shaker entirely, with the introduction of the electric blender. By the mid-1860s, the use of a pair of tumblers to mix drinks was common practice. The patent history involves improvements on this practice:
