Dazzle Camouflage

We think of camouflage as what animals use to blend in with their background. A ship that has zebra stripes that aren't even straight is not what a normal person would call camouflage.  But a still photo doesn't do it justice, because ships are always in motion, and the enemies looking for our ships are seeing it in motion. If a ship sits still, it's probably not in a battle zone. 

Razzle Dazzle camouflage was developed in World War I in response to submarines attacking them with torpedoes. In order to understand the mechanism behind the idea, we have to put ourselves in the place of an enemy submarine aiming a torpedo. The bedazzled ship doesn't have to be invisible; it just has to be hard to destroy. Did it work? Not as well as hoped for, but any edge is worth the effort to save a battleship and its huge crew. Half as Interesting takes us through the steps behind the design. The camouflage ends around 5:35; the rest is an ad for a good cause.
