The Myth - Metal body piercings attract lightning.
Verdict - Busted
Notes - The lightning did seem to strike the dummy with a piercing more, but not the piercings directly. It would take a piercing the size of a doorknob to attract lightning. Given that the realistic piercings did not get struck, the myth was technically busted. Adam was also shown having his tongue pierced, but he did not keep the piercing after the test was concluded.
