Right, we’re going to need some help with this. If you’re a magician, you’ve just become our best friend.

After the jump you’ll see a video from street magician Dynamo. He’s a bit like David Blaine in a way, except he doesn’t draw eyes on his hands and therefore isn’t as much of a tit. But we digress.

In the video, Dynamo does one of those old tricks where he switches one banknote for another one that’s locked away in a bag. You’ll have seen the trick a million times before. What we want to know is this: how does it work? Watch the video below and put an end to our misery. It’s sending us potty.
