Wooden or steel?

Picture
Roller coasters can be two types; wooden or steel. You'll notice a big difference in the ride depending on the type of material used. Wooden coasters are non-looping. They're also not as tall and not as fast, and they don't usually acquire very steep hills or as long a track as steel ones do. Wooden coasters do offer one advantage over steel coasters, assuming you're looking for palm-sweating thrills, they sway a lot more due to the material used. Tubular steel coasters allow more looping, higher and steeper hills, greater drops and and much greater speeds.
