Today, when you order "Optical Brainwave trick Barrie Richardson", you'll instantly be emailed a Penguin Magic gift certificate. You can spend it on anything you like at Penguin, just like cash. Just complete your order as normal, and within seconds you'll get an email with your gift certificate.
Effect: Any card is freely called out and then a deck of ordinary cards are removed from their case and fanned faces showing, one card is seen to be turned face down. It is the card that was named. Astounding! The cards can then be used again for other card tricks!
A waste of money unfortunately. I would recommend Alvo's version of the invisble deck rather than
this. Optical Brainwave appears to be out of stock at the moment, I don't think penguin should
bother ordering anymore in!
