Spray Can.2

Actual Elapsed Time: 1/10th of a second

A thin sheet of water streams out of a spray bottle and then breaks up into tiny droplets. Normally, we can only see the fine droplets produced by a spray can or bottle. But by slowing the action down 100 times, we can view the subtle transition the liquid undergoes as it enters the air. At first, the liquid is held together by a force called surface tension. But as the stream spreads out, surface tension no longer holds the liquid together and the stream breaks up.

How This Clip Was Made:

This slow-motion video was created using a special video camera that takes 250 images a second, as opposed to only 30 images a second for a normal video camera. The video was then digitized and transferred to a computer. The action was slowed down even more by displaying each image twice. Footage provided by: NAC Visual Systems.
