The design of roller coasters can vary widely, with some featuring wooden structures while others are made of steel. The primary purpose of a roller coaster is to provide excitement and entertainment. Many roller coasters are equipped with safety features, such as harnesses and brakes, to ensure the safety of riders. Popular examples of roller coasters include Steel Vengeance and Fury 325, which are known for their height and speed.
