A half pipe is a structure commonly used in extreme sports like skateboarding, snowboarding, and freestyle skiing. It features two steeply curved ramps facing each other, connected by a flat bottom. There are plenty of synonyms for a half pipe, including a bowl, ramp, vert ramp, mini ramp, quarterpipe, spine ramp, pool, and transition. These structures offer athletes a unique opportunity to perform aerial tricks and maneuvers by using the curved walls to generate speed and momentum. Half pipes come in different sizes and configurations, but all provide the same thrill and excitement for those brave enough to take them on.
