Driving is the controlled operation and movement of a land vehicle, such as a car, truck or bus.
Although direct operation of a bicycle and a mounted animal are commonly referred to as riding, such operators are legally considered drivers and are required to obey the rules of the road. Driving over a long distance is referred to as a road trip.
The world's first long distance road trip by automobile took place in Germany in August 1888 when Bertha Benz, the wife of Karl Benz, the inventor of the first patented motor car (the Benz Patent-Motorwagen), travelled from Mannheim to Pforzheim (a distance of 106 km / 66 miles) in the third experimental Benz motor car (which had a maximum speed of 10 mph/16 km/h) and back, with her two teenage sons Richard and Eugen but without the consent and knowledge of her husband. Her official reason was that she wanted to visit her mother but unofficially she intended to generate publicity for her husband's invention (which had only been used on short test drives before), which succeeded as the automobile took off greatly afterwards and the Benz's family business eventually evolved into the present day Mercedes-Benz company.
Ice cubes are small, roughly cube-shaped pieces of ice, conventionally used to cool beverages. Ice cubes are sometimes preferred over crushed ice because they melt more slowly; they are standard in mixed drinks that call for ice, in which case the drink is said to be "on the rocks."
Ice cubes that are crushed or sheared into irregularly-shaped flakes may add an interesting aesthetic effect to some cocktails. Crushed ice is also used when faster cooling is desired, since the rate of cooling is governed by the number and average radius of the ice particles.
Melting ice cubes sometimes precipitate white flakes, commonly known as "floaties". This is calcium carbonate which is present in many water supplies and is completely harmless.[citation needed]
American physician and humanitarian John Gorrie built a refrigerator in 1844 with the purpose of cooling air. His refrigerator produced ice which he hung from the ceiling in a basin. Gorrie can be considered the creator of ice cubes, but his aim was not to cool drinks: he used the ice to lower the ambient room temperature. During his time, a dominant idea was that bad air quality caused disease. Therefore, in order to help treat sickness, he pushed for the draining of swamps and the cooling of sickrooms.
