Bicycle invisible deck

Effect

Imagine:
having an invisible deck of cards become visible and proving it by also having the freely selected invisible card instantly become visible as well
having a spectator call a friend who eerily names the one card you have turned over in the deck prior to the call
Or, many, many other uses.

"The ridiculously low price, combined with the incredible reactions it gets, is why I think this simple card trick is one of the best, ever. You can adapt it to any kind of performance once you know the secret; the sky is the limit." -The Daily Magician, Reviewer
