Alpine skiing is a sport where you travel to a mountain that has snow and you use specialised hard boots, called ski boots, which attach to skis, long planks of wood, carbon or various other materials, by bindings. You slide down the snow covered hill on your skis. If you want to learn how to ski, I would highly recommend taking lessons. There is a whole technique to skiing properly and if you learn correctly, you are much less likely to hurt yourself or other people.

A half pipe is a U-shaped structure that you use the boost ball to launch off of. Charge your boost and relase it when you are just about to head up the ramp part. immediately begin charging again, and release when you are about to head up the opposite side. This builds up both momentum and charge so you can reach astounding heights.
