Kirby Wire
A Kirby wire is a pendulum-based flying system used by stage performers. The system was invented by George Kirby in 1898,''Academic Dictionary of Film, Television and Theatre'', pg. 177. and utilizes a quick-release mechanism for safety. The Kirby family made other innovations in theatrical flight including the somersault wire and a system that allowed an actor to be flown to the stage above the audience.

Pendulum
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the period. The period depends on the length of the pendulum and also to a slight degree on the amplitude, the width of the pendulum's swing. From the first scientific investigations of the pendulum around 1602 by Galileo Galilei, the regular motion of pendulums was used for timekeeping and was the world's most accurate timekeeping technology until the 1930s. The pendulum clock invented by Christiaan Huygens in 1658 became the world's standard timekeeper, used in homes and offices for 270 years, and ac ...

Somersault
A somersault (also ''flip'', ''heli'', and in gymnastics ''salto'') is an acrobatic exercise in which a person's body rotates 360° around a horizontal axis with the feet passing over the head. A somersault can be performed forwards, backwards or sideways and can be executed in the air or on the ground. When performed on the ground, it is typically called a roll. Types Body positions Somersault may be performed with different positions, including tucked, piked (bent at the hips), straddled, and layout (straight body). Direction The sport of tumbling does not require participants to combine both front and back elements, and most tumblers prefer back tumbling as it is easier to build momentum. Arabian saltos begin backwards, continue with a half twist to forwards, and end with one or more saltos forwards. They can be trained by beginning with an Arabian dive roll and adding a front salto to it. They are counted as front tumbling in women's artistic gymnastics and back tum ...

Circus Equipment
A circus is a company of performers who put on diverse entertainment shows that may include clowns, acrobats, trained animals, trapeze acts, musicians, dancers, hoopers, tightrope walkers, jugglers, magicians, ventriloquists, and unicyclists as well as other object manipulation and stunt-oriented artists. The term ''circus'' also describes the performance which has followed various formats through its 250-year modern history. Although not the inventor of the medium, Philip Astley is credited as the father of the modern circus. In 1768, Astley, a skilled equestrian, began performing exhibitions of trick horse riding in an open field called Ha'Penny Hatch on the south side of the Thames River, England. In 1770, he hired acrobats, tightrope walkers, jugglers and a clown to fill in the pauses between the equestrian demonstrations and thus chanced on the format which was later named a "circus". Performances developed significantly over the next fifty years, with large-scale theatr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Special Effects
Special effects (often abbreviated as SFX, F/X or simply FX) are illusions or visual tricks used in the theatre, film, television, video game, amusement park and simulator industries to simulate the imagined events in a story or virtual world. Special effects are traditionally divided into the categories of mechanical effects and optical effects. With the emergence of digital film-making a distinction between special effects and visual effects has grown, with the latter referring to digital post-production and optical effects, while "special effects" refers to mechanical effects. Mechanical effects (also called practical or physical effects) are usually accomplished during the live-action shooting. This includes the use of mechanized props, scenery, scale models, animatronics, pyrotechnics and atmospheric effects: creating physical wind, rain, fog, snow, clouds, making a car appear to drive by itself and blowing up a building, etc. Mechanical effects are also often inco ...
