Brazil's Globo TV network has released video of Paulo David Amorim demonstrating how metal objects seem drawn to him. Forks, knives and scissors appear to remain stuck on his body.
A doctor who examined the boy said he's never seen anything like it in 30 years of practicing medicine. He also said the boy's health is not at risk.
The boy's father tells Globo that he decided to test his son after learning of a boy in Croatia with a similar ability.
