What is Cobra roll?
[[File:The Hulk Coaster (5143123646).jpg|thumb|The '''cobra roll''' in The Incredible Hulk roller coaster at Universal Studios Islands of Adventure.]] A '''cobra roll''' is a part of a [[roller coaster]]. It is a [[double-inversion]] and it looks like the shape of a striking [[cobra]]'s head. A cobra roll has two half-vertical loops facing the same direction joined together by two half corkscrews that each twist in opposite directions. The coaster train enters the cobra roll' low, completes the first half loop, then turns [[perpendicular]] into a half corkscrew, completing a first inversion. This is immediately followed by another half corkscrew that twists in the opposite direction into the other half vertical loop, completing a second inversion and exiting the '''cobra roll''' traveling in the opposite direction from which it entered.<ref name=USA>{{cite news|publisher=USA Today|url=https://www.usatoday.com/picture-gallery/travel/experience/america/theme-parks/2019/05/09/roller-coasters-most-inversions/1143583001/|title=These roller coasters will throw you for a loop|date=May 9, 2019|access-date=January 23, 2021}}</ref> ==References== {{reflist}} [[Category:Roller coasters]]
