Hot Air Balloon
A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon (closest to the burner flame) is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, thou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Battle Of Legnica
The Battle of Legnica (), also known as the Battle of Liegnitz () or Battle of Wahlstatt (), was fought between the Mongol Empire and combined European forces at the village of Legnickie Pole (''Wahlstatt''), approximately southeast of the city of Legnica in the Duchy of Silesia on 9 April 1241. A combined force of Poles and Moravians under the command of Duke Henry II the Pious of Silesia, supported by feudal nobility and a few knights from military orders sent by Pope Gregory IX, attempted to halt the Mongol invasion of Poland.

Kongming Lantern
A sky lantern (), also known as Kǒngmíng lantern (), or Chinese lantern, is a small balloon made of paper, with an opening at the bottom where a small fire is suspended. Sky lanterns have been made for centuries in cultures around the world, to be launched for play or as part of long-established festivities. The name ''sky lantern'' is a translation of the Chinese name but they have also been referred to as ''sky candles'' or ''fire balloons''. Several fires have been attributed to sky lanterns, with at least two 21st-century cases where deaths occurred. Sky lanterns have been made illegal in several countries such as Vietnam which has banned the production, sale, and release of sky lanterns throughout the country since 2009. Many areas of Asia do not permit sky lanterns because of widespread fire hazards as well as danger to livestock. Construction The general design is a thin paper shell, which may be from about 30 cm to a couple of metres across, with an opening ...

Three Kingdoms
The Three Kingdoms of Cao Wei, Shu Han, and Eastern Wu dominated China from AD 220 to 280 following the end of the Han dynasty. This period was preceded by the Eastern Han dynasty and followed by the Jin dynasty (266–420), Western Jin dynasty. Academically, the periodisation begins with the establishment of Cao Wei in 220 and ends with the conquest of Wu by Jin in 280. The period immediately preceding the Three Kingdoms, from 184 to 220, was marked by chaotic infighting among warlords across China as Han authority collapsed. The period from 220 to 263 was marked by a comparatively stable arrangement between Cao Wei, Shu Han, and Eastern Wu. This stability broke down with the conquest of Shu by Wei in 263, followed by the usurpation of Cao Wei by Jin in 266 and ultimately the conquest of Wu by Jin in 280. The Three Kingdoms period including the collapse of the Han was one of the most dangerous in Chinese history due to multiple plagues, widespread famines, and civil war. A n ...
