THE strange talent of a 6-year-old boy has scientists scratching their heads in Croatia.
Little Ivan is able to attract metal objects to his chest.
The boy's unique abilities are strongest in the morning or when he's calm.
It's believed Ivan can hold more than 20kg of metal on his chest.
His parents say he's always been a little strange after walking at 8 months and rollerblading at just 15 months.
