Question: What roller coaster in Mumbai, India features five track turns that put riders upside-down? 
Context: A Wild Mouse roller coaster (also Mad Mouse or Crazy Mouse) is a type of roller coaster characterised by small cars that seat four people or fewer and ride on top of the track, taking tight, flat turns (without banking) at modest speeds, yet producing high lateral G-forces.  The track work is characterised by many turns and "bunny hops", the latter producing abrupt negative vertical G forces.  When approaching a turn from a straight section the intended impression is that one will simply continue straight, and thus plunge off of the device, this since there are no transition sections as are in a conventional high speed coaster track and the turn itself is obscured upon close approach.  Almost all Wild Mice feature "switchback" sections, consisting of several of these unbanked turns, separated by straight sections.  Usually the turns on the switchback section are 180°, but some coasters feature 90° turns as well as more rarely steep runs with loops (for example Crazy Mouse at Tobu Zoo in Japan, which is no longer operating).  Some riders, usually among taller people, report sustaining whiplash after being subjected to these turns. A wooden roller coaster is most often classified as a roller coaster with running rails made of flattened steel strips mounted on laminated wooden track.  Occasionally, the support structure may be made out of a steel lattice or truss, but the ride remains classified as a wooden roller coaster due to the track design.  Because of the limits of wood, wooden roller coasters, in general, do not have inversions (when the coaster goes upside down), steep drops, or extremely banked turns (overbanked turns).  However, there are exceptions; the defunct Son of Beast at Kings Island had a 214 ft drop and originally had a 90 ft loop until the end of the 2006 season, although the loop had steel supports.  Other special cases are Hades 360 at Mount Olympus Water and Theme Park in Wisconsin Dells, Wisconsin.  The coaster features a double-track tunnel, a corkscrew, and a 90-degree banked turn.  There is also The Voyage at Holiday World (an example of a wooden roller coaster with a steel structure for supports) featuring three separate 90-degree banked turns.  Ravine Flyer II at Waldameer Park has a 90-degree banked turn, T Express at Everland in South Korea with a 77-degree drop, and Outlaw Run at Silver Dollar City which has 3 inversions and 120-degree overbanked turn. Millennium Force is a steel roller coaster built by Intamin at Cedar Point amusement park in Sandusky, Ohio, United States.  It was the fourteenth roller coaster to be built at the park since Blue Streak opened in 1964.  Upon completion in 2000, Millennium Force broke six world records and was the world's first Giga Coaster, a roller coaster that exceeds 300 ft in height and completes a full circuit.  It was briefly the tallest and fastest in the world until Steel Dragon 2000 opened later the same year.  The ride is also the third-longest roller coaster in North America after The Beast at Kings Island and Fury 325 at Carowinds.  It was the first roller coaster to use a cable lift system rather than a traditional chain lift.  The coaster has a 310 ft , 45-degree lift hill with a 300 ft drop and features two tunnels, three overbanked turns, and four hills.  It has a top speed of 93 mph . Nitro is a steel Floorless Coaster at the Adlabs Imagica amusement park located in Khopoli, Mumbai, India.  Manufactured by Bolliger & Mabillard, the roller coaster reaches a maximum height of 132 ft and a maximum speed of 65.2 mph .  The coaster also features five inversions.  Nitro opened to the public in October 2013. Roller coaster phobia is a colloquial and slang term describing an individual's fear of roller coasters.  While roller coasters are the most popular theme park attraction, certain people feel nauseated, afraid, dizzy, or unsafe when riding roller coasters.  In the majority of cases, this fear is related to acrophobia, claustrophobia, or a traumatic event.  Roller coaster phobia can be overcome relatively easily, the best cure being going on the tallest/fastest roller coaster before riding roller coasters of a lesser magnitude.  Roller coaster phobia has been linked to previously experiencing an accident, vertigo, and fear of heights.  In rare cases, riders may be afraid of roller coasters due to a painful ride, tight restraints, being thrown around in the restraints, and excessive g-forces on the body of the rider. A roller coaster inversion is a roller coaster element in which the track turns riders upside-down and then returns them to an upright position.  Early forms of inversions, dating as far back as 1848 on the Centrifugal Railway in Paris, were vertical loops that were circular in nature.  They produced massive g-force that was often dangerous to riders, and as a result, the element eventually became non-existent with the last rides to feature the looping inversions being dismantled during the Great Depression.  In 1975, designers from Arrow Development created the corkscrew, reviving interest in the inversion during the modern age of steel roller coasters.  Since then, the element have evolved from simple corkscrews and vertical loops to more complex inversions such Immelmann loops and cobra rolls. Featuring fourteen inversions, The Smiler at Alton Towers holds the world record for the number of inversions on a roller coaster. Iron Rattler is a steel roller coaster located at Six Flags Fiesta Texas in San Antonio, Texas.  The ride opened in 2013, replacing The Rattler, a wooden roller coaster, by putting a new steel track on top of The Rattler's wooden support structure.  The distance between the lowest and highest points of the first drop was increased from 124 to and the drop was made steeper by changing the angle to 81 degrees.  The resulting modifications increased the speed of the trains from 65 to .  It is the first hybrid wood and steel roller coaster to feature an inversion, in which riders are turned upside-down and then back upright.  The inversion is a zero-g-roll, which is when the train goes through a combination of a loop and a roll. Outlaw Run is a wooden roller coaster located at the Silver Dollar City amusement park in Branson, Missouri.  The ride was the first wooden roller coaster manufactured by Rocky Mountain Construction and the first wooden roller coaster with multiple inversions, in which riders are turned upside-down and then back upright.  The 2937 ft ride features three inversions and a top speed of 68 mph , making "Outlaw Run" the sixth-fastest wooden roller coaster in the world.  The 162 ft first drop of the ride is the fourth steepest in the world among wooden roller coasters, at 81° beyond horizontal. A flying roller coaster is a type of roller coaster meant to simulate the sensations of flight by harnessing riders in a prone position during the duration of the ride.  The roller coaster cars are suspended below the track, with riders secured such that their backs are parallel to the track.  Flying roller coasters come in a variety of sizes and designs depending on the intended demographic for the ride.  Some flying roller coasters are intended for children and, thus, are relatively slow and gentle; others are meant for older children and adults and can be very fast and intense. White Cyclone (ホワイトサイクロン , Howaito Saikuron ) is a wooden roller coaster at Nagashima Spa Land in Mie Prefecture, Japan.  At 1700 m in length, White Cyclone is the third longest wooden roller coaster in the world, and is the longest wooden roller coaster outside of the United States.  Despite its length, White Cyclone is still considerably shorter than the 2479 m Steel Dragon 2000, the world's longest steel roller coaster, which is also at Nagashima Spa Land.  In addition to being the third longest wooden roller coaster, White Cyclone is the seventh tallest wooden roller coaster in the world and the fourth tallest wooden roller coaster outside the United States.  A single ride on the White Cyclone costs ¥1,000 (approximately $9 USD), and the ride is restricted to those individuals above 1.3 m in height; and those individuals under 54 years of age.
