I love internet hoaxes. Especially the ones that hang on for so long because there’s no real credible science to hang your skeptical hat on. For example, one of the most procreated hoaxes, both inside the internet and out, is the myth of the cell-phone-cause gas station explosion. This has become so much a part of popular culture that the industry has put warning labels on fuel pumps warning of this non-existent threat.
