Height rules

Most big slides ask you to be at least 1.20 m or 1.40 m tall. That's not to be mean, it's so the ride fits you properly and you can hold on.Typical minimums: 48 in (Summit Plummet), 120 cm (AquaLoop), 1.40 m (Insano). Kansas had no height requirement for water rides until 2017. New slides are trialled with sandbag or water-filled dummies before staff ride them; Action Park's Andy Mulvihill rode the Cannonball Loop in hockey pads.
