Cheating and Illusions

To respects the rights of magical creators, we do not condone exposure of copyrighted illusions. The magical effects and techniques presented here are believed to be common knowledge or classics which are not privately owned.


The art of an illusionist is to produce extraordinary "effects". What the spectator sees seems impossible mostly because some of the causes are cleverly hidden. Something wonderful is essentially created by cheating. Elsewhere on this site, we discuss many of the wonderful things that can be experienced without cheating in the mathematical or physical universe. Some of that can be so surprising that a magician could present it without trickery (mathematical magic). Yet, a scientist should be acquainted with some of the techniques magicians use to fool people in order to debunk false science.

Also, it's just entertaining to investigate those things. A spectator trained in magic will not be so easily fooled and will often be able to explain away many "new" tricks in terms of basic techniques. Likewise, a trained scientist may think of causes or mechanisms which provide explanations for new observations. To paraphrase Martin Gardner, the Universe itself may well be a huge magical trick waiting to be explained...


(2009年03月22日) Deceit (Lying)

Because lying is usually neither acceptable nor expected, magicians do get away with it. Lying is simply part of their trade and people keep believing them...

For example, an illusionist who uses a stacked deck will routinely flash it for a quick inspection to "conclude" that the cards are not ordered in any special way. The exact opposite is true, of course, but people will normally assume that whatever they are told is true, unless proven otherwise. Lying is the crudest form of psychological manipulation. It's very effective.


(2009年03月22日) Misdirection

Misdirection is the act of focusing the attention of the spectator away from the point where a dubious action is taking place. It is one way to hide things more effectively and can be construed as a subtle form of nonverbal deception.

Chop-Chop Wheatley (2009年03月26日) Chop Cup

This effect uses a gimmicked cup whose basic design is named after Alvin H. Wheatley (1901-1964) an australian-born magician performing in oriental garb as Tung Pin Soo or "Chop-Chop". On stage Wheatley used a bamboo gaffed cup.

The idea of incorporating a magnet in a cup designed for magic effects seems much older than that... It appears in the expanded version (1723) by M. Grandin of the work first published by Jacques Ozanam's (1640-1718) as Récréations mathématiques et physiques (1694).

(2009年03月24日) Force and Reveal
Forcing is giving the illusion of a free choice.

If the magician forces a choice, he will not have any trouble guessing what it was!

A choice can be forced either by substitution or reduction. In the former case, a chosen item is substituted for another before whoever made the choice is even aware of the outcome of that choice. One example is the ribbon spread force were the spectator points to the back of a card in a pack spread before him. The magician moves the bottom card underneath the chosen card under the pretense of squaring the deck before turning it over at the chosen point, thus forcing the bottom card to be "chosen" every time.

(2009年03月29日) Knot a Problem
Tying a knot on a rope without letting go of the ends.

There are two ways to solve this problem. One of them is honest (purely mathematical) whereas the other uses deceit and sleight of hand (to hide the fact that you are letting go of one end.

The honest way to proceed is to cross your arms before you graps the ends of the rope... As you uncross your arms, a knot forms on the rope! 3 ropes of unequal length become equal.

(2009年03月28日) This 'n' That
A well-designed card trick devised by Paul Annett (a.k.a, nicepaul).

This popular trick appeared on YouTube on 2007年02月05日 xxx with the following narrative:

A guy came up to me in the street the other day and he said: Look, I've got a little game that I'd like to play with three playing cards. We've got THIS card, THIS card and THAT card. He said: "All you've going to do is keep an eye on THAT card. As he said that, he moved it to the bottom of the pile.

  • I saw him do it and I said: "Easy THAT card is on the bottom."
  • "No, That's THIS card."
  • I said: "Fine, well if THIS card is on the bottom, THAT card must be on the top."
  • He said: "No, that's also THIS card."
  • I said: "Eh, THIS card is the bottom and the top. THAT card must be in the middle."
  • He said: "No, that's also THIS card."
  • I said: "Well, that's not fair 'cause you're using three of THIS card."
  • He said: "No, THAT card is on the bottom."
  • ...
  • You get a little bit of THIS you get a little bit of THAT, but you get not much of the OTHER.

(2015年02月25日) Bill Simon's Prophecy Move
Simon originally called this effect Business Card Prophecy.
