Gravitron
The Gravitron (also known as the Starship, Starship 2000, Starship 3000, Starship 4000, Starship Area 51, Starship Gravitron, Starship Exodus, Alien Abduction, Alien Invasion, Twister, Devil's Hole, Area 51, and Enterprise) is an amusement ride, most commonly found as a portable ride at fairs and carnivals.
 The Gravitron first appeared at Morey's Piers in 1983 and quickly became a fixture at amusement parks in many countries.
 It is a modification of an earlier ride called the Rotor.
 The ride was originally designed and manufactured by Wisdom Industries, though several examples of the Gravitron were produced under license by ARM in the UK and Ferrari in Australia.
Rotor (ride)
The Rotor is an amusement park ride, designed by German engineer Ernst Hoffmeister in the late 1940s.
 The ride was first demonstrated at Oktoberfest 1949, and was exhibited at fairs and events throughout Europe during the 1950s and 1960s.
 The ride still appears in numerous amusement parks, although travelling variants have been surpassed by the Gravitron.
Kamikaze (ride)
A Kamikaze (also known as a Double-Arm Ranger, The Apollo, or the Skymaster, scissors and Sky Flyer) is a pendulum amusement ride, usually found as a traveling ride, with some examples found at amusement parks.
 The ride is manufactured by FarFabbri & Sartori, and first made its debut in 1984.
 Since then, over 150 Kamikazes have been sold. Roller coaster
A roller coaster is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopes, and sometimes inversions.
 People ride along the track in open cars, and the rides are often found in amusement parks and theme parks around the world.
 LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, related to the Switchback Railway that opened a year earlier at Coney Island.
<ref> Olympia Looping
Olympia Looping, also known as Munich Looping, is a portable steel roller coaster designed by Anton Schwarzkopf and built by BHS.
 It is the largest portable roller coaster in the world, and the only one with five inversions.
 It appears at many carnivals in Germany, most notably Oktoberfest, where it made its debut in 1989.
 It is named for its five vertical loops, which resemble the Olympic rings.
 Although they are clothoid-shaped, their shape is closer to circular than the ones on most other roller coasters, so they exert unusually high "g"-forces on the passengers (up to 5.2 g).
 The entire structure weighs 900 tons and requires a space 85 m wide by 36 m deep.
 The ride usually runs with five cars per train, though at events such as Oktoberfest and Winter Wonderland in Hyde Park, London, it runs with seven to increase throughput in busy periods. Flying Scooters
Flying Scooters, also known simply as "Flyers", is an amusement ride consisting of a center post with ride vehicles suspended from arms attached to the center post.
 The ride dates back to the 1930s and 1940s when Bisch-Rocco manufactured the ride.
 In the early 2000s, Larson International revived the concept and is the sole manufacturer of these rides. Wonder Mountain's Guardian
Wonder Mountain's Guardian (also known as "Guardian" or "WMG"; during Halloween Haunt known as "Zombies 4D") is a 4D, interactive dark ride roller coaster at the Canada's Wonderland amusement park located in Vaughan, Ontario, Canada.
 It is also the first ride part of Cedar Fair's Amusement Dark collection.
 Park management first proposed a dark ride located inside Wonder Mountain around 2004.
 Technology and budget limitations at the time delayed the project's planning and design stages until 2011.
 The steel track was manufactured by Art Engineering; it is approximately 1000 ft long and has a maximum height of about 60 ft .
 The ride also has one of the largest drop tracks in the world. Bayern Kurve
The Bayern Kurve is an amusement ride made in both a portable and park model that debuted in 1965 and was invented by German engineer Anton Schwarzkopf.
 During the ride, riders sit in one of the sixteen bobsled-themed cars that travel at a high-speed around a circular single-hilled track.
 Riders start in an upright position and as the cars pick up speed, they tilt inward toward the center of the ride.
 This ride is also known for its loud horn which is similar to that of a diesel train engine that blasts its loud roar when the ride reaches maximum speed.
 Also akin to a train, the seamed track creates the same rail "click-clack" railway sound, particularly at the lower section of track in the front.
 Additionally, the ride has a distinct whine that increases with speed due to its tire/blade drive. Holiday Park, Germany
Holiday Park is an amusement park in Haßloch, Germany.
 It is one of Germany's most popular theme parks (receiving about a million visitors per year) and is part park and part woodland.
 Its Free Fall Tower was the first amusement ride of its kind in Europe.
 The Park also offers several roller coasters, including Expedition GeForce, water rides, and live shows. Puss In Boots‘ Giant Journey
