Wingsuit flying involves using a suit with fabric that creates air resistance to glide through the air after jumping from an airplane. Bungee jumping connects jumpers to an elastic cord so they can jump from tall structures and bounce back up. Skiing uses skis attached to boots to travel across snow, while surfing involves slipping into waves while standing on a surfboard. These extreme sports involve jumping from heights, sliding across terrain, or riding waves and all provide thrills by testing gravity and human limits.
