Levitating Magician Dynamo stunned Londoners with his trick sponsored by Pepsi Max. How was he able to levitate alongside a double-decker bus?

The popular British illusionist named Dynamo appeared to levitate outside of a double-decker bus as it drove through Westminster, ABC News reports. His right arm was outstretched and his hand was touching the side of the bus. With his left hand, he was holding a cell phone. He even wiggles his legs in the air to prove he wasn't standing on anything.

The trick shocked pedestrians. Some chased the bus to record the event on their cell phones, and others stared in amazement. Questions and speculation flooded social media about the video posted on Youtube of the spectacle.

On Facebook, posters argued how the stunt was pulled off.

Yahoo! News explains how Dynamo might have been able to achieve the magic trick. Australia's news.com.au Facebook page writes that Dynamo's arm was actually a steel prosthetic that was attached to the bus. A harness strapped to Dynamo's body kept him elevated, while his hand was tucked inside.

"His fingers don't move in the clip and there are no people around when he hovers up and down the bus," the news site wrote. "In fact, at second glance the arm attached to the bus looks pretty phony."
