Snowball
A snowball is a spherical object made from snow, usually created by scooping snow with the hands, and pressing the snow together to compact it into a ball. Snowballs are often used in games such as snowball fights. A snowball may also be a large ball of snow formed by rolling a smaller snowball on a snow-covered surface. The smaller snowball grows by picking up additional snow as it rolls. The terms "snowball effect" and "snowballing" are derived from this process. The Welsh dance " Y Gasseg Eira" also takes its name from an analogy with rolling a large snowball. This method of forming a large snowball is often used to create the sections needed to build a snowman. The underlying physical process that makes snowballs possible is sintering, in which a solid mass is compacted while near the melting point. Scientific theories about snowball formation began with a lecture by Michael Faraday in 1842, examining the attractive forces between ice particles. An influential early explanati ...

Snowball Fight
A snowball fight is a physical game in which balls of snow are thrown with the intention of hitting somebody else. The game is similar to dodgeball in its major factors, though typically less organized. This activity is primarily played during winter when there is sufficient snowfall. Two examples of organized games involving snowball fights are Yukigassen and SheenAab Jung. Yukigassen (雪合戦) is a snowball fighting-competition from Japan. SheenAab Jung (aka 'Snow Fighting') is played in Jammu and Kashmir of India. History Legal prohibition In 1472, the city council of Amsterdam allegedly prohibited snowball fights for reasons of public safety, a prohibition which occasionally finds its way into lists of strange laws. The law, if it ever existed, is not presently enforced. Several localities have passed ordinances prohibiting snowball fights, typically as part of a larger prohibition on thrown missiles. In 2018, the town council of Severance, Colorado unanimously over ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbara Sleigh
Barbara Grace de Riemer Sleigh (1906–1982) was an English children's writer and broadcaster. She is remembered most for her Carbonel series about a king of cats. Family and career Barbara Sleigh was born on 9 January 1906 in Birmingham, the daughter of an artist, Bernard Sleigh, and his wife Stella, née Phillp, who had married in 1901. Both parents came from a Methodist background, but she was brought up an Anglican. The family moved to Chesham for a time, then back to Birmingham. Their marriage broke up in about 1914. Her older brother, Brocas Linwood Sleigh (1902–1965), would also become a writer. Having attended art college and teachers' training college, Sleigh taught in various schools before joining the teacher training department at Goldsmiths College in London in 1929. She went to work for the BBC programme '' Children's Hour'' in 1932. There, in 1935, she married a colleague, David Davis (1908–1996) at Dunchurch, Warwickshire, but BBC house rules at the time wo ...

The Snowball (children's Novel)
''The Snowball'' (first published 1969) is a domestic fantasy novel for children by the English writer Barbara Sleigh Barbara Grace de Riemer Sleigh (1906–1982) was an English children's writer and broadcaster. She is remembered most for her Carbonel series about a king of cats. Family and career Barbara Sleigh was born on 9 January 1906 in Birmingham, the d ... (1906–1982), who is best known for her Carbonel series. The two main human characters are Tom Tickle, aged eight, and his sister Tilda, aged six. The story The story is set in a small house on the edge of a small English country town. The children are on a loose rein, as their mother is soon called away to nurse some relations of theirs through a bout of measles, leaving them with their preoccupied father, a schoolmaster who is busy writing a book (p. 10). Snow starts to fall almost immediately after Mrs Tickle leaves. The children spend the day making a snowman – Tom's work – and a snow-woman – Tilda's wo ...

Snowball Effect
A snowball effect is a process that starts from an initial state of small significance and builds upon itself, becoming larger (graver, more serious), and also perhaps potentially dangerous or disastrous (a vicious circle), though it might be beneficial instead (a virtuous circle). This is a cliché in cartoons and modern theatrics and it is also used in psychology. The common analogy is with the rolling of a snowball down a snow-covered hillside. As it rolls the ball will pick up more snow, gaining more mass and surface area, and picking up even more snow and momentum as it rolls along. In aerospace engineering, it is used to describe the multiplication effect in an original weight saving. A reduction in the weight of the fuselage will require less lift, meaning the wings can be smaller. Hence less thrust is required and therefore smaller engines, resulting in a greater weight saving than the original reduction. This iteration can be repeated several times, although the decreas ...

Ball Ice
Ice eggs, or ice balls, are a rare phenomenon caused by a process in which small pieces of sea ice in open water are rolled over by wind and currents in freezing conditions and grow into spheroid pieces of ice. They may collect into heaps of balls or 'eggs' on beaches. The gentle churn of water, blown by a suitably stiff breeze makes concentric layers of ice form on a seed particle that then grows into the floating ball as it rolls through the freezing currents. Given enough time, the frozen balls can grow to become boulder size. In 2016, giant snowballs washed up on a beach in Siberia, some measuring a metre (about 3 feet) across. An ice specialist from the Finnish Meteorological Institute has been quoted as saying ice balls are rare but not unprecedented, and occur about once a year on the Finnish coastline as conditions allow. They also appear on the American Great Lakes where they are called Ice balls. See also * Yukimarimo - Wind blown balls of fine frost accum ...

Yukimarimo
Yukimarimo are balls of fine frost formed at low temperatures on the Antarctic plateau during weak wind conditions. Yukimarimo were discovered in 1995 at Dome F by the 36th Japanese Antarctic Research Expedition (JARE-36) at temperatures of –59 to –72 °C. Electrostatic attraction between ice crystals explains the formation of yukimarimo at these low temperatures. Name Yukimarimo were named by T. Kameda on JARE-36 in 1995. "Yuki" means snow in Japanese, and "marimo" is a ball-like growth of water algae which the yukimarimo resemble. Formation During a storm on the Antarctic plateau, humidity rises above normal levels. After a storm, the temperature drops rapidly and, due to the excess humidity, hoarfrost forms on the surface of the snow. At these low temperatures, electrostatic attraction between the rapidly formed ice crystals is high, due to growth charging during formation. When a light wind blows after the formation of this hoarfrost, the hoarfrost breaks apar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Denivation
Niveo-aeolian or cryo-aeolian deposition is the process by which fine-grained sediments are transported by wind and deposited on or mixed with snow or ice. The wind sweeps the snow and sand grains into aeolian landforms such as ripples, and further sorts the snow and ice grains into distinct layers. When snow melts or sublimates, the sediments are redeposited onto the surface below., forming patterns known as denivation features. Niveo-aeolian deposition is most widespread in polar climates, but may be found anywhere that is at least seasonally below freezing. In most places, much or all of the snow in these niveo-aeolian deposits melts in the spring or summer. However, "perennial" niveo-aeolian deposits have been observed in Antarctica's Victoria Valley. Initially, after the wind has deposited it, the surface of a niveo-aeolian deposit typically consists of a rippled bedform of mixed sand and snow. Beneath the surface, the deposits commonly consist of alternating layers of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
