A simple folded paper plane Folding instructions for a traditional paper dart. A paper plane (also known as a paper airplane or paper dart in American English, or paper aeroplane in British English) is a toy aircraft, usually a glider, made out of a single folded sheet of paper or paperboard.
Time published an April 2, 1973 article, The Paper-Plane Caper, [2] about the paper airplane and its Kline–Fogleman airfoil. Also in 1973, CBS 60 Minutes did a 15-minute segment on the KF airfoil. CBS reran the show in 1976. [citation needed] In 1985, Kline wrote a book entitled The Ultimate Paper Airplane. [3]
Pan American Airways offered to fly designs of paper airplanes that originated in Japan to the contest. He entered and, out of 12,000 entries from 28 countries, won in two categories: duration and distance. [3] His designs have sold millions throughout Japan and the world. He is the author of a multi-volume work on high-performance paper ...
Compasses are usually made of metal or plastic, and consist of two "legs" connected by a hinge which can be adjusted to allow changing of the radius of the circle drawn. . Typically one leg has a spike at its end for anchoring, and the other leg holds a drawing tool, such as a pencil, a short length of just pencil lead or sometimes a
Diagonal pliers (also known as wire cutters or diagonal cutting pliers, or under many regional names) are pliers intended for the cutting of wire or small stock, rather than grabbing or turning. The plane defined by the cutting edges of the jaws intersects the joint rivet at an angle or "on a diagonal", giving pliers their name.
Chinese paper cutting, in a style that is practically identical to the original 6th-century form. Jianzhi (Chinese: 剪紙, pinyin: jiǎnzhǐ) is a traditional style of papercutting in China, and it originated from cutting patterns for rich Chinese embroideries and later developed into a folk art in itself.
The aircraft are light and stubby so as to maneuver quickly in the air. Each has a 8 ft 2 in (2.5 m) crepe paper streamer attached to the rear of the aircraft by a 3 m (9.8 ft) string. Each pilot attacks only the other aircraft's streamer, to attempt to cut it with their propeller or wing. Each cut scores 100 points.
Cutting tool materials must be harder than the material which is to be cut, and the tool must be able to withstand the heat and force generated in the metal-cutting process. Also, the tool must have a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the ...
