Paper Popper
A paper popper is a party prank that is commonly used in schools. There are many variations of a paper popper, but they all involve a folded sheet of paper being gripped and right down. This causes air to be forced into the paper's holes, making the paper flaps pop out in the opposite direction, then making a loud popping noise. According to popular misconception, the sound is supposed to be caused by the paper breaking the sound barrier. In actuality, what happens is that air rushes in a blast wave to fill the vacuum created in the pocket that opens. The sound is described as the crack of a whip, which is an example of breaking the sound barrier, although the causes are different. Most papers work for poppers, although some are louder and some are quieter than others.

Origami Paper Popper Type1
) is the Japanese art of paper folding. In modern usage, the word "origami" is often used as an inclusive term for all folding practices, regardless of their culture of origin. The goal is to transform a flat square sheet of paper into a finished sculpture through folding and sculpting techniques. Modern origami practitioners generally discourage the use of cuts, glue, or markings on the paper. Origami folders often use the Japanese word ' to refer to designs which use cuts. On the other hand, in the detailed Japanese classification, origami is divided into stylized ceremonial origami (儀礼折り紙, ''girei origami'') and recreational origami (遊戯折り紙, ''yūgi origami''), and only recreational origami is generally recognized as origami. In Japan, ceremonial origami is generally called "origata" ( :ja:折形) to distinguish it from recreational origami. The term "origata" is one of the old terms for origami. The small number of basic origami folds can be combin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Party
A party is a gathering of people who have been invited by a host for the purposes of socializing, conversation, recreation, or as part of a festival or other commemoration or celebration of a special occasion. A party will often feature food and beverages, and often conversation, music, dancing, or other forms of entertainment. Some parties are held in honor of a specific person, day, or event, such as a birthday party, a Super Bowl party, or a St. Patrick’s Day party. Parties of this kind are often called celebrations. A party is not necessarily a private occasion. Public parties are sometimes held in restaurants, pubs, beer gardens, nightclubs, or bars, and people attending such parties may be charged an admission fee by the host. Large parties in public streets may celebrate events such as Mardi Gras or the signing of a peace treaty ending a long war.

Prank
A practical joke, or prank, is a mischievous trick played on someone, generally causing the victim to experience embarrassment, perplexity, confusion, or discomfort.Marsh, Moira. 2015. ''Practically Joking''. Logan: Utah State University Press. A person who performs a practical joke is called a "practical joker" or "prankster". Other terms for practical jokes include gag, rib, jape, or shenanigan. Practical jokes differ from confidence tricks or hoaxes in that the victim finds out, or is let in on the joke, rather than being talked into handing over money or other valuables. Practical jokes are generally lighthearted and without lasting effect; they aim to make the victim feel humbled or foolish, but not victimized or humiliated. Thus most practical jokes are affectionate gestures of humour and designed to encourage laughter. However, practical jokes performed with cruelty can constitute bullying, whose intent is to harass or exclude rather than reinforce social bonds throu ...

Sound Barrier
The sound barrier or sonic barrier is the large increase in aerodynamic drag and other undesirable effects experienced by an aircraft or other object when it approaches the speed of sound. When aircraft first approached the speed of sound, these effects were seen as constituting a barrier, making faster speeds very difficult or impossible. The term ''sound barrier'' is still sometimes used today to refer to aircraft approaching supersonic flight in this high drag regime. Flying faster than sound produces a sonic boom. In dry air at 20 °C (68 °F), the speed of sound is 343 metres per second (about 767 mph, 1234 km/h or 1,125 ft/s). The term came into use during World War II when pilots of high-speed fighter aircraft experienced the effects of compressibility, a number of adverse aerodynamic effects that deterred further acceleration, seemingly impeding flight at speeds close to the speed of sound. These difficulties represented a barrier to flying ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paper Plane
A paper plane (also known as a paper airplane in American English or paper aeroplane in British English) is a toy aircraft, usually a glider made out of single folded sheet of paper or paperboard. A simple nose-heavy paper plane, thrown like a dart, is also known as a paper dart. History The origin of folded paper gliders is generally considered to be of ancient China, although there is equal evidence that the refinement and development of folded gliders took place in equal measure in Japan. Certainly, manufacture of paper on a widespread scale took place in China 500 BCE, and origami and paper folding became popular within a century of this period, approximately 460–390 BCE. It is impossible to ascertain where and in what form the first paper aircraft were constructed, or even the first paper plane's form. For over a thousand years after this, paper aircraft were the dominant man-made heavier-than-air craft whose principles could be readily appreciated, though thanks to ...

Paper Toys
Paper toys are toys made of paper. They are constructed in several ways, by folding, as in paper airplanes, paper fortune tellers or Origami, or by cutting, decorating or assembling pieces of paper with glue or tape to create a paper doll or paper model. History Paper toys date back to ancient times. The history of paper toys can be traced back to the art of origami (or-i-GA-me).The word is based on the Japanese words ''Ori'', which means to fold, and ''Kami'', which means paper. However origami's roots are from China and it spread to Japan somewhere around the sixth century. The craft was for only the rich at first because the cost of paper was very high. They found useful ways to use the folded paper. For example, they would fold it with strips of dried meat or fish and this was called Noshi, which was a token of good luck. Also they would often wrap the glasses of wine at a wedding into butterfly form to represent the bride and groom. As time went by new methods of ma ...
