Heads, I Win. Tails, You Lose! by David Devlin

A really strong piece of mentalism that is impromptu and can be performed literally in every single performing situation is not too easy to find. This, however, fits the bill beautifully.

Effect: The mentalist places a business card onto the table. The audience is told that there is a prediction underneath the business card, but that it will not be shown to them until later. The performer reaches into his pocket (or wherever) and brings out three invisible coins: a nickel, a quarter, and a dime. The spectator is told to imagine that she sees them. The performer lays the imaginary coins in a row on the table.

The spectator uses her imagination to select one of the coins. Let's say she selects the quarter. She then, using her imagination, flips the invisible quarter into the air. She then calls out whether the quarter landed heads or tails side up. Say she picks heads. The card is then removed, and underneath the card is a quarter! Not only that, but the quarter is marked to prove that the mentalist knew the outcome of the coin toss from the beginning!

This is David's beautiful approach to Max Maven's "Positive/Negative". Several changes have been made from the original routine. The features include:

  • No switches of any kind
  • Only one prediction
  • Nothing is written
  • No gimmicks of any kind
  • 99% impromptu (all you need is any kind of cover such as a card or an opaque tumbler, any coin, and a Sharpie Marker)
  • Nothing is stolen away
  • Nothing is hidden
  • Absolutely everything is examinable and ungimmicked
  • Everything may be given away to the spectator to keep
  • Perfect for walk around, table hopping, formal close up, and even on STAGE!
  • No sleight of hand whatsoever
  • Only one coin is under the cover
You are going to love this and use is every chance you get!

I prefer this to Max Maven's version. I've used this many times as an impromptu effect in bars and restaurants. All you need is to either be prepared for the reveal, or just carry or borrow a sharpie.

Okay, here's another variant on Max Maven's Positive/Negative. It follows the same presentation/techniques as the half-dozen other versions that I have (E + MO, for those in the know), but the reveal is different. And it's not bad. I like Scott Guinn's versions better, but this is an acceptable alternative. Interestingly, Rick Lax uses a similar method for one reveal in his "which hand" routine, Quarterly Report, and Penguin charges a lot more for it. At $5, this is a good purchase if you like Positive/Negative.
