SHARK-B-GONE

摘要

In 2005, Eric Stroud, the managing partner of Shark Defense, a New Jersey company that specializes in shark repelling technologies, happened to be carrying a rare-earth magnet as he passed a tank full of sharks. The sharks fled, and Stroud took note. After further tests, Stroud and his colleagues found that sharks that came within 20 inches of rare-earth magnets similar to the one he had been carrying would consistently swim away.
