unorthodox solution when the bus is full

English master illusionist Dynamo the Magician takes David Copperfield's repertoire a leap further, and this trick should appeal to rush hour commuters in a big city, particularly as it would avoid paying a fare...

How was this actually done? This explanation seems the most plausible: "his right arm touching the bus isn't real, and is made of metal/plastic. This allows the palm of the fake arm to be welded/strongly glued to the bus. The fake arm would connect to a well hidden harness that would hold his weight and distribute it in such a way so that he's level, and his real right arm is tucked by his side."
