Action Origami
Action origami is origami that can be animated. The original traditional action model is the flapping bird. Models of which the final assembly involves some special action, for instance blowing up a water bomb, are also typically classed as action origami. Rarer models like the paper plane and spinners which have no moving parts are included. Traditional action origami occasionally involved cuts, but modern models typically are constructed without them. Action origami are usually toys built to amuse, but some are designed to inspire wonder. Action toys Action toys include birds or butterflies with flapping wings, beaks that peck, and frogs that hop, as well as popular traditional models like the fortune teller. Paper poppers or bangers are models that make a noise when flicked down hard. Some action origami is designed to accompany a story whilst it is built. Complex models Some models are far too complex to be classified as toys. They are built to amaze and astonish. For insta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cootie Catcher
A fortune teller (also called a cootie catcher,.. chatterbox,. salt cellar, whirlybird, or paku-paku) is a form of origami used in children's games. Parts of the fortune teller are labelled with colors or numbers that serve as options for a player to choose from, and on the inside are eight flaps, each concealing a message. The person operating the fortune teller manipulates the device based on the choices made by the player, and finally one of the hidden messages is revealed. These messages may purport to answer questions (hence the name) or they may be activities that the player must perform. The same shape may also be used as pincers or as a salt cellar. Construction A paper fortune teller may be constructed by the steps shown in the illustration below:. # The corners of a sheet of paper are folded up to meet the opposite sides and (if the paper is not already square) the top is cut off, making a square sheet with diagonal creases. # The four corners of the square are folded ...

Origami
) is the Japanese paper art, 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.

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 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.

Robert J
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can be use ...

Miura Fold
The is a method of folding a flat surface such as a sheet of paper into a smaller area. The fold is named for its inventor, Japanese astrophysicist Kōryō Miura. The crease patterns of the Miura fold form a tessellation of the surface by parallelograms. In one direction, the creases lie along straight lines, with each parallelogram forming the mirror reflection of its neighbor across each crease. In the other direction, the creases zigzag, and each parallelogram is the translation of its neighbor across the crease. Each of the zigzag paths of creases consists solely of mountain folds or of valley folds, with mountains alternating with valleys from one zigzag path to the next. Each of the straight paths of creases alternates between mountain and valley folds.. Reproduced in ''British Origami'', 1981, and online at the British Origami Society web site. The Miura fold is related to the Kresling fold, the Yoshimura fold and the Hexagonal fold, and can be framed as a generalizati ...

Electroactive Polymers
file:EAP-example2.png, (a) Cartoon drawing of an EAP gripping device.(b) A voltage is applied and the EAP fingers deform in order to release the ball.(c) When the voltage is removed, the EAP fingers return to their original shape and grip the ball An electroactive polymer (EAP) is a polymer that exhibits a change in size or shape when stimulated by an electric field. The most common applications of this type of material are in actuators and sensors. A typical characteristic property of an EAP is that they will undergo a large amount of deformation while sustaining large forces. The majority of historic actuators are made of ceramic piezoelectric materials. While these materials are able to withstand large forces, they commonly will only deform a fraction of a percent. In the late 1990s, it has been demonstrated that some EAPs can exhibit up to a 380% strain, which is much more than any ceramic actuator. One of the most common applications for EAPs is in the field of robotics in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shape-memory Polymer
Shape-memory polymers (SMPs) are polymeric smart materials that have the ability to return from a deformed state (temporary shape) to their original (permanent) shape when induced by an external stimulus (trigger), such as temperature change. Properties of shape-memory polymers SMPs can retain two or sometimes three shapes, and the transition between those is often induced by temperature change. In addition to temperature change, the shape change of SMPs can also be triggered by an electric or magnetic field, light or solution. Like polymers in general, SMPs cover a wide range of properties from stable to Synthetic biodegradable polymer, biodegradable, from soft to hard, and from elastic to rigid, depending on the structural units that constitute the SMP. SMPs include thermoplastic and thermoset (covalently cross-linked) polymeric materials. SMPs are known to be able to store up to three different shapes in memory. SMPs have demonstrated recoverable strains of above 800%. Two im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
