We’re used to the sight of victorious athletes biting their medals, but the Paralympics this year has thrown up a new trend.

You may have noticed winners in Rio holding up their medals to their ears – and there’s a very good reason for it.

Every medal has tiny steel balls inside it so when they’re shaken they make a noise.

And the sound is individual to the colour of the medal, with golds containing 28 balls, compared with 20 in the silver and 16 in the bronze, meaning the podium-toppers can get a louder noise out of their bling than anyone else.

Pretty cool, huh?

It means athletes with visual impairments get a more complete experience from their medals than they would have done otherwise.

And what’s more, they also contain the words “Rio 2016 Paralympic Games” in Braille.

We’re gonna go ahead and call that the best medal we’ve ever seen. Or heard.
