Lawn Mower

Lawn Mower

Now you can mow your lawn with knowledge with these lawn mower facts!

  • Lawn mowers are mechanical or robotic devices used to cut grass, often lawns or grass fields, using blades.
  • Lawn mowers can be powered by hand, electricity or a fuel motor.
  • Lawn mower blades generally spin on a vertical or horizontal axis, and are named ‘rotary mowers’ and ‘reel mowers’ respectively.
  • Lawn mowers were first patented in 1830, by Englishman Edwin Budding, from England’s Gloucestershire in Europe, to replace the scythe, and Budding’s invention was inspired by the cloth cross-cutting machines that were used in the local mills.
  • Reel lawn mowers often have three to seven ribbon like blades that are connected together in a cylindrical formation, while those with rotary blades are typically limited to one relatively flat blade that attaches to the underneath of the machine.

  • Steam powered lawn mowers were first patented in 1893 by James Sumner in England, although they could only be used after a few hours of heating to allow for pressure buildup.
  • Lawn mowers can propel items like stones, at high speed, that can cause damage, and while many other mowing related injuries can be prevented from wearing correct footwear, in 2004, at least 80,000 people in the United States were injured by mowers or mowing activity.
  • Many lawn mowers emit high quantities of pollution, comparable to domestic cars, and often produce loud noises that can be irritating and damage hearing.
  • Lawn mowers often consist of a motor, blades and a box called a ‘catcher’ that collects grass cuttings, although hand powered reel bladed machines typically have blades and a handle, and sometimes a catcher, although a motor is absent.
  • Ride-on mowers, that allow for a person to sit on the machine, are useful for mowing large areas, while robotic lawn mowers are becoming increasingly popular and only require minimal human interaction.

Croissant

Croissant

Do you eat croissants for breakfast?

  • Croissants are puffy bakery food items that are typically flaky and buttery in texture, that are usually tan or light brown in colour.
  • Croissants are said to have been derived from a yeast-dough pastry named ‘kipfel’, in Austria, Europe, that may have its origins as early as the 1200s, although it is possible that they did not exist until the 1600s.
  • Croissants are mainly made with butter and a bread like dough containing yeast, and can be filled and flavoured with numerous foods including chocolate, nut, ham, cheese, dried fruits and apple
  • Croissants are traditionally crescent in shape, but can be spherical or cylindrical, and the typical shape is said to have originated from the Austrian kipfel.
  • Croissants are popularly eaten during breakfast, commonly sold as a type of fast food, and are often sold frozen so that they can be thawed and heated at home.

  • There are many legends regarding the history of the croissant, and the most popular is that it originates in the late 1600s, when bakers created crescent shaped pastries based on the Turkish flag, due to the Turks having been defeated by their enemies.
  • The term ‘croissant’ was named after the French word for ‘crescent’, referring to the traditional shape.
  • While the origin of croissants is uncertain, they were probably introduced to France in the late 1830s, by officer August Zang from Austria, in a bakery that he owned and was located in France’s Paris, in Europe.
  • Croissants are typically made by folding butter into dough, rolling the dough into sheets, and then continuing the folding and rolling process known as ‘laminating’, before cutting and rolling into a crescent shape and baking in an oven.
  • Croissants have significant quantities of sodium, selenium, folate and thiamin and are also high in fat.
