It is manufactured by Zierer and is the first major steel coaster located at Knoebels since the Whirlwind which closed in 2004.[1] Riders are restrained by a lap bar only which comes across the legs and the waist. The ride features small, 8 passenger trains, resulting in a low capacity. The ride starts off by rounding a bend and then climbing the 98 ft (30m) lift hill. The train then proceeds to go straight down and into the first inversion, a cobra roll. The train then goes into a vertical loop followed by a series of twists and turns around the vertical lift hill until it enters the final inversion, a zero g roll. The train then goes into a short, but intense, helix before the brake run and into the station. The complete ride is one minute and twenty seconds. Riders can also purchase a photograph of themselves on the roller coaster after the ride is through. HistoryThe park was looking for a new roller coaster since 2004 when Whirlwind (now Bocaraca) was closed and shipped to a new park in Costa Rica and with push by park visitors for a new Roller Coaster.[2] So the park enlisted the help of Zierer Rides a German coaster builder for the design. The actual design of the ride didn't start until 2009. Due to the Financial crisis of 2007–2008, Construction of the parts began in July 2013 and was assembled at the park in late February 2015 and construction being complete by April 2015. Impulse replaced the Bumper Boats ride, which was purchased from Rocky Glen Park in Moosic, Pennsylvania in the 1980s. Elements{{main|Roller coaster elements}}
