Magician David Blaine stunned onlookers at a New York restaurant by smashing a glass, and proceeding to eat it piece by piece.

The renowned illusionist was recently out dining with a group of friends, including professional poker player Phil Ivey, at the Tao eaterie, when Ivey asked Blaine to provide some unusual entertainment, in return for $10,000 (£5,000).

A source tells the New York Daily News: "David was doing a bunch of tricks, but Phil wanted to see something spectacular. He offered David $10,000 to eat a glass from the table."

So Blaine broke a large glass and then ate every shard, much to the horror of fellow diners.

And the star's representative confirmed that the stunt was genuine, saying: "This did happen and was completely real."
