Reserved B.S. (Billet Switch) by Koch Magic

(c. 2019) (Submit Review) (Submit Update)

This is based upon Bob Ostin’s Dice Prediction c. 1953. And is quite similar to Nelson’s Mental Gimic. However, the difference between Bob Koch’s version and both the original and Nelson’s is that it uses gravity instead of a spring or rubber band.  This makes is less likely to break, but also means that it can make more of a sound and is less versatile. 

The unit is the most solid of all the versions I have seen and is very easy to switch out for other items such as billets, notes, and bills.

Effect: Reserved B.S. is a simple utility device that lets you switch cards, currency, a prediction or even a coin, right under the spectator’s nose. It’s based on Bob Ostin’s brilliant Dice Prediction effect.

It’s a stand you’d see on a restaurant table with a card that says, “RESERVED”, the table number, or the specials of the day.

Imagine having the stand on display with a playing card clamped in the clip. A spectator selects and signs a card. The card is vanished, burned or lost in the deck. With no false moves, you pluck the card from the clip and hand it to them. They unfold it and it’s their signed card.
