The girl with magnetic hands
Tuesday, September 14th, 2010
A Serbian schoolgirl has amazed
medics with her astonishing
magnetic hands.
Ten-year-old Jelena Momcilov has been picking
up cutlery, coins and even metal furniture by
just touching them at her family home in
Zeljusa, since she first discovered her powers
five years ago.
Now experts at nearby Nis University have urged
scientists to investigate, reports CEN.
“I’d say this is a kind of unknown bio-magnetism.
More experts would need to join me and
research what this is all about,” said
department head Pavle Premovic.
