In an exclusive clip from Wednesday's premiere episode, "Fear of Falling 335 Feet," Kari Byron and Tory Belleci use themselves as test subjects as they take the plunge down Florida's Busch Gardens' Falcon's Fury, the tallest freestanding ride in North America at 335 feet.
Emotions run high in the clip as the ride pulls the hosts up hundreds of feet, with Belleci asking Byron, "What did you have for breakfast?"
"You're about to find out," she responds.
The series will follow the hosts as they tackle adventures like racing IndyCars, plummeting down the world's tallest water slide and jumping out of airplanes – all while delving into the engineering, physics and biomechanics that explain "the science behind the fun," according to the network.
