I haven't seen Penn & Teller for ages!
I remember them captivating me when I was younger. I had an interest in magic but knew very little and I was convinced by some of the explanations.
One explanation I retold for years, until I got into magic and realised that the explanation was so utterly obviously wrong. But so convincing! I cringed at the thought of telling so many people over the years.
Mind you, things haven't changed because I still tell it. It works as a kind of smoke screen now, if you will.
It was an explanation as to how a chosen card could be guessed.
It was simple - In an off-beat moment, Teller fanned the cards, perfectly, towards the camera.
This was only for a split second, but it was enough to allow a computer to glance at every single index in the pack and deduce which card was missing.
Then, the computer transmitted the answer to a huge electronic billboard on the other side of the road.
How simple.
Doh.
