Bouncing Bullets Off Water

With the right shot, it’s possible to skip a bullet off water, as shown in this video from the Slow Mo Guys. The angle of the bullet relative to the water needs to be quite shallow, as this sets the bullet up for the hydrodynamic lift needed to skip. Physically, the mechanism for skipping a bullet is similar to rock-skipping. The bullet’s impact creates a cavity that the bullet rides. With the right conditions, the cavity orients the bullet upward, creating the lift needed to skip. (Video and image credit: The Slow Mo Guys)
