Cannonball Drop was a new obstacle that appeared in American Ninja Warrior 9. It was the second obstacle of the Los Angeles qualifying course. Competitors must grab onto a 9-inch diameter cannonball and ride it down a track similar to that of the Log Grip. The track is slightly steeper at the start, making the cannonball accelerate, and the track also has two drops that test the grip strength of the competitor. During the Red Nose Day Special, all of the celebrities attempted a slightly easier version, and all were able to complete it. During qualifying, a total of 28 competitors fell here.
