Snowboard halfpipe: Snowboard halfpipe is a snowboard competition in which the competitors starts individually from the top of a halfpipe.  The half-pipe is a semi-circular ditch or purpose built ramp (that is usually on a downward slope), between 8 and 22 feet (6.7 m) deep.  Competitors perform tricks while going from one side to the other and while in the air above the sides of the pipe.  The halfpipe discipline is scored by judges with one overall impression score based on the following criteria: execution of tricks, variety of tricks, difficulty, pipe use, and amplitude.

Street unicycling: Street unicycling is one of the latest developments in unicycling.  The aim of the sport is to use natural/urban/specially made obstacles such as ledges, handrails and stairs in a given area to perform tricks that look good.  The emphasis falls on technical proficiency, style and creativity.  Street unicycling draws inspiration from skateboarding and bmx bike riding, with many similar tricks.

Wilberforce pendulum: A Wilberforce pendulum, invented by British physicist Lionel Robert Wilberforce around 1896, consists of a mass suspended by a long helical spring and free to turn on its vertical axis, twisting the spring.  It is an example of a coupled mechanical oscillator, often used as a demonstration in physics education.  The mass can both bob up and down on the spring, and rotate back and forth about its vertical axis with torsional vibrations.  When correctly adjusted and set in motion, it exhibits a curious motion in which periods of purely rotational oscillation gradually alternate with periods of purely up and down oscillation.  The energy stored in the device shifts slowly back and forth between the translational 'up and down' oscillation mode and the torsional 'clockwise and counterclockwise' oscillation mode, until the motion eventually dies away.

Big air: Big air is a sports discipline where the competitor rides a vehicle (such as a snowboard, a skateboard, a ski or a motocross motorcycle) down a hill and perform tricks after launching off very large jumps.  It is an extreme version of slopestyle.  Competitors perform complex tricks in the air, aiming to attain sizable height and distance as well, all while securing a clean landing.  Many competitions also require the rider to do a specific trick to win the major prize.

Monkey Knuckles: Monkey Knuckles is a skill toy consisting of two sliding wooden balls on a string, with end stoppers that allow the player to grip the toy.  The toy can be manipulated in a variety of ways to perform tricks, and depending on the way that the player grasps and manipulates the toy, different styles of play are possible.  Monkey Knuckles was developed by Matthew Hiebert, and was patented in 2006.  In 2013 Hiebert licensed the design to Yomega Corp., which took over its manufacturing and distribution.  In 2015, Kuma Films released a YouTube video featuring Monkey Knuckles.

Slinky: A Slinky is a toy precompressed helical spring invented by Richard James in the early 1940s.  It can perform a number of tricks, including travelling down a flight of steps end-over-end as it stretches and re-forms itself with the aid of gravity and its own momentum, or appear to levitate for a period of time after it has been dropped.  These interesting characteristics have contributed to its success as a toy in its home country of United States, resulting in many popular toys with slinky components in a wide range of countries.

Begleri: Begleri (Greek: μπεγλέρι) is a small skill toy consisting of one or more beads at either end of a short string or fine chain.  The toy can be flipped and twirled around the fingers to perform tricks.  Begleri originated in Greece, and originally derived from the Greek rosary or komboloi, which serve the function of worry beads, and are often flipped around to pass the time or keep the hands busy.  While komboloi have beads forming a closed circle, begleri beads are threaded on an open strand, usually in a symmetrical formation, with equal weighting at either end.  Begleri come in many forms, consisting of semi-precious stone or metal beads.  They can be similar in form to the percussion instrument kashaka, but are much smaller in size.

Master of Illusion (video game): Master of Illusion, known in Europe as Magic Made Fun: Perform Tricks That Will Amaze Your Friends!  and in Japan as Magic Encyclopedia (マジック大全 , Majikku Taizen ) , is a magician video game for the Nintendo DS.  It was developed and published by Nintendo, released in Japan on November 16, 2006, November 26, 2007 in North America and March 14, 2008 in Europe.  Several of its magic tricks were made available over the Nintendo DSi's DSiWare download service.
