Bungee jumping: an activity that involves jumping from a tall structure while connected to a large elastic cord. The tall structure is usually a fixed object, such as a building or bridge. (I think a cliff or something could work here too, just saying)
Sky diving: The sport of jumping out of a plane (which we don't have. Muggle thing that gets you up way higher than I think I've seen a broom go) and into a free fall, usually characterized by air acrobatics before safely releasing a parachute to stop said free fall and bring us slowly to the ground.
