Harry Houdini

Getting out of a pair of handcuffs was one of Harry Houdini's oldest tricks. In 1904, during a performance in London, the illusionist was manacled in a pair on which a blacksmith had spent five years perfecting the locking mechanism, claiming "no mortal man" could pick it. It took Houdini more an hour and 10 minutes to get out of them.

An overcrowded hall with curious children and adults holding their breaths welcomed the famous illusionist DMC, who made a real show of undoubted talent at the Sofia Science Festival on Friday.

The magician, whose tricks appears on the National Geographic Channel, on several occasions called on the spectators to pursue their dreams.
