In this edition of "A World of Difference," Korey Kiepert, owner and engineer with The Gravity Group, goes through the 8 main types of roller coasters and breaks down how they work as well as the decisions behind why they get built in the first place. Korey explains the difference between a giga coaster and a strata coaster, as well as what separates a "wild mouse" from a "mine train."
