A new car color every day? I'd settle for one that hides the salt

The American Society of Metals International has a feature on its Web site called Materials Radio. This is really a series of podcasts on materials and their uses targeted at middle school students. ASM asked its University student Material Advantage members to pass along their knowledge of materials by creating short audio programs that are informative, entertaining and easy to understand. The latest one is rather interesting. It is about a paint technology emerging from the labs that uses electromagnetics to change color on demand. The example given is one where a football fan changes his car to team colors on game day.

Of course, Detroit Lions or Cleveland Browns fans would be more likely to hide their affiliation after last season's results. Those of us in the upper midwest might use this idea to make our cars salt-colored to better blend in with the grime.
