In this shocking video from a ski slope in southwestern Russia, a seemingly fun and harmless activity quickly went tragically wrong. Trace Gallagher explained the particulars on America Live. The giant inflatable ball was rolled down a gradual slope with two men strapped inside, but what you don't see off to the left is a cliff. As the ball makes its way down it gets caught up in the wind as onlookers desperately race through the snow to try to stop it from going over the edge.

It eventually did plummet off the cliff, and the two men inside fell out and were rescued by skiers. One of the men tragically died from his injuries while the other remains hospitalized.
