Projects in High-Speed Photography
In this shot, the BB was actually captured by the elastic strip. This happens just about as often as a clean puncture. Perhaps the elastic is slightly thicker or stronger in some places than others, thereby leading to a capture. The result also depends on the speed of the BB. At higher speeds, the BB always pierces the strip.
Note the drop of milk suspended from the bottom of the strip. This shows how still that part of the strip was, even as the center region was being stretched to many times its normal length.
Find out what happens as the captured BB stretches the strip to the breaking point.
A multiple-image photograph of a collision shows the deceleration of the BB.
