Invisible Pack (Blue Bicycle)
One of the most amazing card trick effects, and easy to master!
The spectator is given an invisible pack to shuffle and reverse any card they like. They then throw the imaginary pack back to the magician who shows it has turned into a real pack. The chosen card is now actually reversed in the pack.
The pack can be in full view all the time and no sleight of hand is required.
The pack is produced in Bicycle playing cards.
