		Title: Collapse of underwater cavity ID #: HS-34cmp © copyright: Loren M. Winters Medium: 35mm negative Description: side-by-side images showing collapse of an underwater cavity trailing a BB fired into water Technique: single-burst flash Category: Hydrodynamics	Title: Head-on path of BB in water ID #: HS-32-16 © copyright: Loren M. Winters Medium: 35mm negative Description: BB fired into water on collision course with camera. Corrugations in the interface between water and air can be seen. Technique: single-burst flash Category: Hydrodynamics
		Title: Spinning pellet fired into water at Mach 1 ID #: smed-01 © copyright: Loren M. Winters Medium: 35mm negative Description: 0.177 in pellet fired from a rifled barrel at Mach 1 into tank of water. The upper portion of the cavity is reflected from the under surface of the water. Technique: single-burst flash Category: Hydrodynamics	Title: BB fired into water tank ID #: HS-41-14 © copyright: Loren M. Winters Medium: 35mm negative Description: BB splits the water as it moves downward in a tank. The cavity expands outward at first (yellow to green images) and then collapses to form a small cavity just behind the BB (blue image). Technique: color-sequenced multiflash (interval = 1.33 ms) Category: Hydrodynamics
		Title: Deceleration of a BB in water I ID #: MP-2-23 © copyright: Loren M. Winters Medium: 35mm negative Description: BB entering water at 233 m/s forms a cavity which expands outward at first and then begins to collapse. The deceleration of the BB can be modeled using a v² drag force. Technique: multiflash with image sweep, right-to-left (interval = 0.300 ms) Category: Hydrodynamics	Title: Cavity collapse ID #: MP-3-17 © copyright: Loren M. Winters Medium: 35mm negative Description: in later stages of BB's deceleration in water, the cavity splits and collapses Technique: multiflash with image sweep, right-to-left (interval = 0.300 ms) Category: Hydrodynamics
		Title: Deceleration of a BB in water (color) ID #: MP-4-16 © copyright: Loren M. Winters Medium: 35mm negative Description: formation and collapse of the cavity behind a BB decelerating in water Technique: multiflash with image sweep, right-to-left (interval = 0.400 ms) Category: Hydrodynamics	Title: Deceleration of plastic ball in water ID #: kssb-15 © copyright: Loren M. Winters Medium: 35mm negative Description: 2.54-cm diameter hard plastic ball fired into a tank of water at 11 m/s. In the first image, the ball is breaking the water's surface. Technique: color-sequenced multiflash (interval = 13.00 ms) Category: Hydrodynamics
		Title: Path of a ball in water ID #: MK-2-4 © copyright: Loren M. Winters Medium: 35mm negative Description: 2.54-cm diameter ball, fired into water at 7.6 m/s, slows to a halt. The ball, being less dense water, will eventually resurface. The first two images show the ball before entering the water. Technique: color-sequenced multiflash (interval = 10.00 ms) Category: Hydrodynamics
