SKY DIVING DEMO WITH VERTICAL WIND TUNNEL





SKY DIVING DEMO/INDOOR SKY DIVING/ VERTICAL WIND TUNNEL A vertical wind tunnel (VWT) is a wind tunnel that moves air up in a vertical column. Unlike standard wind tunnels which have test sections that are oriented horizontally, as experienced in level flight, a vertical orientation enables gravity to be countered by drag instead of lift, as experienced in an aircraft spin or by a skydiver at terminal velocity. Although vertical wind tunnels have been built for aerodynamic research, the most high-profile are those used as recreational wind tunnels, frequently advertised as indoor skydiving or bodyflight, which have also become a popular training tool for skydivers. A recreational wind tunnel enables human beings to experience the sensation of flight without planes or parachutes, through the force of wind being generated vertically. Air moves upwards at approximately 195 km/h (120 mph or 55 m/s), the terminal velocity of a falling human body belly-downwards.
A vertical wind tunnel is frequently called 'indoor skydiving' due to the popularity of vertical wind tunnels among skydivers, who report that the sensation is extremely similar to skydiving.[clarification needed] The human body 'floats' in midair in a vertical wind tunnel, replicating the physics of 'body flight' or 'bodyflight' experienced during freefall.
The first human to fly in a vertical wind tunnel was Jack Tiffany in 1964 at Wright-Patterson Air Force Base located in Greene and Montgomery County, Ohio. In 1982 Jean St-Germain, an inventor from Drummondville, Quebec, sold a vertical wind tunnel concept to both Les Thompson and Marvin Kratter, both of whom went on to build their own wind tunnels. Soon after, St Germain sold the franchising rights to Kratter for $1.5 million.

Originally known as the "Aérodium", it was patented as the "Levitationarium" by Jean St. Germain in the USA in 1984 and 1994 under Patent Nos. 4,457,509 and 5,318,481, respectively.
The first reference, in print, to a Vertical Wind Tunnel specifically for parachuting was published in CANARA (the Canadian Sport Parachuting Magazine) in 1979. St. Germain then helped build two wind tunnels in America. The first vertical wind tunnel, built solely for commercial use, opened in the summer of 1982 in Las Vegas, Nevada. Later that same year, a second wind tunnel opened in Pigeon Forge, Tennessee. Both facilities opened and operated under the name of Flyaway Indoor Skydiving. In 2005 the 15-year Flyaway Manager Keith Fields purchased the Las Vegas facility and later renamed it "Vegas Indoor Skydiving". In the 1990s William Kitchen, an inventor living in Orlando, FL filed patents for a vertical wind tunnel. and founded the US Company "Sky Venture" in July 1998. This tunnel is specifically designed to simulate the free fall skydiving experience.

Popularity grew quickly and the Orlando, FL site was visited by former U.S. President George H.W. Bush. After the initial location continued to rise in popularity, the rights were sold to Alan Metni, who divided the company into a manufacturing and distribution company (Sky Venture) and public experience company (iFly) which now operates or has licensed tunnels to over 80 locations around the world, including 5 cruise ships, with more in the works. Another milestone in vertical wind tunnel history was 'Wind Machine' at the closing ceremonies of the 2006 Torino Winter Olympics This was a custom-built unit by Aerodium (Latvia/Canada) for the closing ceremony. Many people had never seen a vertical wind tunnel before and were fascinated by the flying humans with no wires. A vertical wind tunnel performance in Moscow's Red Square was shown in 2009 during the presentation of the logotype of the Sochi 2014 Winter Olympics. In 2010, a vertical wind tunnel was shown at the Latvian exhibition of Expo 2010 in Shanghai, China.

PREGNANCY EXERCISE Regular aerobic exercise during pregnancy appears to improve (or maintain) physical fitness. Physical exercise during pregnancy does appear to decrease the need for C-section. Bed rest, outside of research studies, is not recommended as there is no evidence of benefit and potential harm. The Clinical Practice Obstetrics Committee of Canada recommends that "All women without contraindications should be encouraged to participate in aerobic and strength-conditioning exercises as part of a healthy lifestyle during their pregnancy". Although an upper level of safe exercise intensity has not been established, women who were regular exercisers before pregnancy and who have uncomplicated pregnancies should be able to engage in high-intensity exercise programs. In general, participation in a wide range of recreational activities appears to be safe, with the avoidance of those with a high risk of falling such as horseback riding or skiing or those that carry a risk

SMITHY SKILL                                                                  https://youtu.be/k6-KsoYYoYE A blacksmith is a metalsmith who creates objects from wrought iron or steel by forging the metal, using tools to hammer, bend, and cut (cf. tinsmith). Blacksmiths produce objects such as gates, grilles, railings, light fixtures, furniture, sculpture, tools, agricultural implements, decorative and religious items, cooking utensils, and weapons. There was a historical opposition between the heavy work of the blacksmith and the more delicate operation of a whitesmith, who usually worked in gold, silver, pewter, or the finishing steps of fine steel. The place where a blacksmith works are called variously a smithy, a forge, or a blacksmith's shop. While there are many people who work with metal such as farriers, wheelwrights, and armorers, in former times the blacksmith had a general knowledge of how to make and repair many things, from the most complex of weapons and armor to sim

TATTOO GIRLS

A tattoo is a form of body modification where a design is made by inserting ink, dyes, and pigments, either indelible or temporary, into the dermis layer of the skin to change the pigment. The art of making tattoos is tattooing. Tattoos fall into three broad categories: purely decorative (with no specific meaning); symbolic (with a specific meaning pertinent to the wearer); and pictorial (a depiction of a specific person or item). In addition, tattoos can be used for identification such as ear tattoos on livestock as a form of branding. The word tattoo, or tattow in the 18th century, is a loanword from the Samoan word tatau, meaning "to strike". The Oxford English Dictionary gives the etymology of tattoo as "In 18th c. tattaow, tattow. From Polynesian (Samoan, Tahitian, Tongan, etc.) tatau. In Marquesan, tatu." Before the importation of the Polynesian word, the practice of tattooing had been described in the West as painting, scarring or staining. The etymology of
