Magicians pull off incredible trick...then show off how they did it

Penn & Teller are a massively famous magic and comedy duo, and they recently performed some magic on James Corden's Late Late Show in the US.

The trick involved Teller being put in a box with Penn breaking the box into three parts only to rebuild it in a different spot.

They had hoped that someone would be able to figure out how they did the trick after only seeing it once, following the premise of their TV show, Penn & Teller Fool Us.
