Fireworks:
Adobe Fireworks is a commercial raster and vector graphics editor hybrid from Adobe that’s available for the Mac and Windows operating systems. Designed specifically for web designers (unlike Photoshop), Fireworks brings you a plethora of tools and options that make full web layout prototyping a breeze.
Among its notable features are: "slices" for slicing and dicing a design mockup into HTML/CSS for rapidly creating prototypes (though you should avoid using auto-generated source code for the end-build), the ability to package an entire site design as a PDF with clickable components for interactive and impressive site prototypes, and optimization tools for making your web graphics as lightweight as possible. _________________ quickbook hosting solutions
Fireworks originated in China some 2,000 years ago. The most prevalent legend has it that fireworks were discovered or invented by accident by a Chinese cook working in a field kitchen who happened to mix charcoal, sulphur and saltpeter (all commonly found in the kitchen in those days). The mixture burned and when compressed in an enclosure (a bamboo tube), the mixture exploded.
Some sources say that the discovery of fireworks occurred about 2,000 years ago, and other sources place the discovery sometime during the 9th century during the Song dynasty (960-1279), although this could be confusion between the discovery of gunpowder by the cook and the invention of the firecracker.
A Chinese monk named Li Tian, who lived near the city of Liu Yang in Hunan Province, is credited with the invention of firecrackers about 1,000 years ago. The Chinese people celebrate the invention of the firecracker every April 18 by offering sacrifices to Li Tian. During the Song Dynasty, the local people established a temple to worship Li Tian.
The firecrackers, both then and now, are thought to have the power to fend off evil spirits and ghosts that are frightened by the loud bangs of the firecrackers. Firecrackers are used for such purposes today at most events such as births, deaths and birthdays. Chinese New Year is a particularly popular event that is celebrated with firecrackers to usher in the new year free of the evil spirits.
Generally Marco Polo is credited with bringing the gunpowder back to Europe in the 13th century, although some accounts credit the Crusaders with bringing the black powder to Europe as they returned from their journeys.
Once in Europe, the black powder was used for military purposes, first in rockets, then in canons and guns. Italians were the first Europeans who used the black powder to manufacture fireworks. Germany was the other European country to emerge as a fireworks leader along with Italy in the 18th century.
The English were also fascinated with fireworks. Fireworks became very popular in Great Britain during the reign of Queen Elizabeth I. William Shakespeare mentions fireworks in his works, and fireworks were so much enjoyed by the Queen herself that she created the position of "Fire Master of England." King James II was so pleased with the fireworks display that celebrated his coronation that he knighted his Fire Master. _________________ computer training
If the rockets powder is kept dry (protected from rain), they should still work. The time from launch to bust is probably too short for any soaking to take place.
That said, with a storm comes strong winds (which could make fireworks to drift off course=danger), and reduced interest from spectators; so there is a good chance it would be postponed. _________________ serviced offices city of london|serviced offices city
Have you ever wondered how this magic works? What is launched into the sky to make these beautiful displays? In this article, you will learn all about firecrackers, sparklers and aerial fireworks.
Just about everyone in the United States has some personal experience with fireworks, either from Fourth of July or New Years Eve celebrations. For example, you have probably seen both sparklers and firecrackers. It turns out that if you understand these two pyrotechnic devices, then you are well on your way to understanding aerial fireworks. The sparkler demonstrates how to get bright, sparkling light from a firework, and the firecracker shows how to create an explosion. _________________ DJs Chicago dj services Chicago
