bet tricks

Magic is a performing art that entertains an audience by creating illusions of impossible[1] or supernatural[2] feats, using purely natural means. These feats are called magic tricks, effects or illusions.
An artist who performs magic is called a magician. Magicians (or magi) are also referred to by names reflecting the type of magical effects they typically perform, such as prestidigitators, conjurors, illusionists, mentalists, ventriloquists, and escape artists, etc.
The term "Magic" is etymologically derived from the Old Persian word Magi. Performances we would now recognize as conjuring have probably been practiced throughout history. The same level of ingenuity that was used to produce famous ancient deceptions such as the Trojan Horse would also have been used for entertainment, or at least for cheating in gambling games, since time immemorial. However, the profession of the illusionist gained strength only in eighteenth century, and has enjoyed several popular vogues.
Jean Eugène Robert-Houdin, the first modern magician.From 1756 to 1781, Jacob Philadelphia performed feats of magic, sometimes under the guise of scientific exhibitions, throughout Europe and in Russia. Modern entertainment magic owes much of its origins to Jean Eugène Robert-Houdin (1805-1871), originally a clockmaker, who opened a magic theatre in Paris in the 1840s. His speciality was the construction of mechanical automata which appeared to move and act as if they were alive. The British performer J N Maskelyne and his partner Cooke established their own theatre, the Egyptian Hall in London's Piccadilly, in 1873. They presented stage magic, exploiting the potential of the stage for hidden mechanisms and assistants, and the control it offers over the audience's point of view. The greatest celebrity magician of all time, Harry Houdini (real name Ehrich Weiss, 1874 - 1926), took his stage name from Robert-Houdin and developed a range of stage magic tricks, many of them based on escapology (though that word was not used until after Houdini's death). The son of a Hungarian rabbi, Houdini was genuinely highly skilled in techniques such as lockpicking and escaping straitjackets, but also made full use of the whole range of conjuring techniques, including fake equipment and collusion with individuals in the audience. Houdini's showbusiness savvy was as great as his performing skill. There is a Houdini Museum dedicated to him in Scranton, Pennsylvania. In addition to expanding the range of magic hardware, showmanship and deceptive technique, these performers established the modern relationship between the performer and the audience.
In this relationship, there is an unspoken agreement between the performer and the audience about what is going on. Unlike in the past, almost no performers today actually claim to possess supernatural powers (although there are exceptions to this, they are regarded as charlatans). It is understood by everyone that the effects in the performance are accomplished through sleight of hand (also called prestidigitation or léger de main), misdirection, deception, collusion with a member of the audience, apparatus with secret mechanisms, mirrors, and other trickery (hence the illusions are commonly referred to as "tricks"). The performer seeks to present an effect so clever and skillful that the audience cannot believe their eyes, and cannot think of the explanation. The sense of bafflement is part of the entertainment. In turn, the audience play a role in which they agree to be entertained by something they know to be a deception. Houdini also gained the trust of his audiences by using his knowledge of illusions to debunk charlatans, a tradition continued by magicians such as James Randi, P. C. Sorcar, and Penn and Teller.
Magic has come and gone in fashion. For instance, the magic show for much of the 20th century was marginalized in North America as largely children's entertainment. A revival started with Doug Henning, who reestablished the magic show as a form of mass entertainment with his distinctive look that rejected the old stereotypes and his exuberant sense of showmanship that became popular on both stage and numerous television specials.
Today, the art is enjoying a vogue, driven by a number of highly successful performers such as David Copperfield, Lance Burton, Penn and Teller, Derren Brown, Barry and Stuart, Criss Angel, Dorothy Dietrich, Greg Frewin and many other stage and TV performers. David Blaine is sometimes included in this category, though his major performances have been more a combination of Houdini-style escape tricks and physical endurance displays than the illusion magic performed by others. The mid-twentieth century saw magic transform in many different aspects: some performers preferred to renovate the craft on stage --- such as The Mentalizer Show in Times Square which dared to mix themes of spirituality and kabbalah with the art of magic --- others successfully made the transition to TV, which opens up new opportunities for deceptions, and brings the performer to huge audiences. A widely accepted code has developed, in which TV magicians can use all the traditional forms of deception, but should not resort to camera tricks, editing the videotape, or other TV special effects --- this makes deception too "easy", in the popular mind. Most TV magicians are shown performing before a live audience, who provide the remote viewer with a (sometimes misleading) reassurance that the effects are not obtained with the help of camera tricks.
Many of the basic principles of magic are comparatively old. There is an expression, "it's all done with smoke and mirrors", used to explain something baffling, but contrary to popular belief, effects are seldom achieved using mirrors today, due to the amount of work needed to install it and difficulties in transport. For example, the famous Pepper's Ghost, a stage illusion first used in 19th century London, required a specially built theatre. Harry Houdini led the field of vanishing large objects, by making an elephant disappear on stage. Modern performers have vanished objects as big as the Taj Mahal, Statue of Liberty, and the Space Shuttle, using other kinds of optical deceptions.
There is much discussion among magicians as to how a given effect is to be categorized, and disagreement as to what categories actually exist -- for instance, some magicians consider "penetrations" to be a separate category, while others consider penetrations a form of restoration or teleportation. It is generally agreed that there are very few different types of effect. While many authors such as Dariel Fitzkee, Harlan Tarbell, S.H. Sharpe and others have disagreed, it has often been said that there are only seven types of illusion[citation needed] (perhaps because it is considered a magic number).
Production The magician produces something from nothing—a rabbit from an empty hat, a fan of cards from thin air, a shower of coins from an empty bucket, or the magician themselves, appearing in a puff of smoke on an empty stage -- all of these effects are productions. Vanishing The magician makes something disappear—a coin, a cage of doves, milk from a newspaper, an assistant from a cabinet, or even the Statue of Liberty. A vanish, being the reverse of a production, may use a similar technique, in reverse. Transformation The magician transforms something from one state into another—a silk handkerchief changes colour, a lady turns into a tiger, an indifferent card changes to the spectator's chosen card. A transformation can be seen as a combination of a vanish and a production. Restoration The magician destroys an object, then restores it back to its original state—a rope is cut, a newspaper is torn, a woman is sawn in half, a borrowed watch is smashed to pieces—then they are all restored to their original state. Teleportation The magician causes something to move from one place to another—a borrowed ring is found inside a ball of wool, a canary inside a light bulb, an assistant from a cabinet to the back of the theatre. When two objects exchange places, it is called a transposition: a simultaneous, double teleportation. Levitation The magician defies gravity, either by making something float in the air, or Magician Anthony Bass levitating a slip of paper.with the aid of another object (suspension)—a silver ball floats around a cloth, an assistant floats in mid-air, another is suspended from a broom, a scarf dances in a sealed bottle, the magician hovers a few inches off the floor. There are many popular ways to create this illusion of the magician himself being levitated, such as the Balducci levitation, the King Rising, Criss Angel's stool levitations, and the Andruzzi levitations. Penetration The magician makes a solid object pass through another—a set of steel rings link and unlink, a candle penetrates an arm, swords pass through an assistant in a basket, a saltshaker penetrates the table-top, a man walks through a mirror. Sometimes referred to as 'solid-through-solid'. Prediction The magician predicts the choice of a spectator, or the outcome of an event under seemingly impossible circumstances—a newspaper headline is predicted, the total amount of loose change in the spectator's pocket, a picture drawn on a slate. Prediction forms the basis for most 'pick-a-card' tricks, where a random card is chosen, then revealed to be known by the performer. Many magical routines use combinations of effects. For example, in the famous 'cups and balls' a magician may use vanishes, productions, penetrations, teleportations and transformations all as part of the one presentation. Lots of magical routines include comedy to go along with the magician's routine which can be very fun for the audience and entertaining for everyone. Some jokes go along with their "Category of Effect" and turn out very nice.
The purpose of a magic trick is to amuse and create a feeling of wonder; the audience is generally aware that the magic is performed using trickery, and derives enjoyment from the magician's skill and cunning. Traditionally, magicians refuse to reveal the secrets to the audience. The reasons include:
Exposure is claimed to "kill" magic as an artform and transforms it into mere intellectual puzzles and riddles. It is argued that once the secret of a trick is revealed to a person, that one can no longer fully enjoy subsequent performances of that magic, as the amazement is missing. Sometimes the secret is so simple that the audience feels let down, and feels disappointed it was taken in so easily. Keeping the secrets preserves the professional mystery of magicians who perform for money. Membership in professional magicians' organizations often requires a solemn commitment to the "Magician's Oath" never to reveal the secrets of magic to non-magicians.
The Magician's Oath (though it may vary, 'The Oath' takes the following, or similar form): "As a magician I promise never to reveal the secret of any illusion to a non-magician, unless that one swears to uphold the Magician's Oath in turn. I promise never to perform any illusion for any non-magician without first practicing the effect until I can perform it well enough to maintain the illusion of magic." Once sworn to The Oath, one is considered a magician, and is expected to live up to this promise. A magician who reveals a secret, either purposely or through insufficient practice, may typically find oneself without any magicians willing to teach one any more secrets.
However, it is considered permissible to reveal secrets to individuals who are determined to learn magic and become magicians. It is typically a sequential process of increasingly valuable and lesser known secrets. The secrets of almost all magical effects are available to the public through numerous books and magazines devoted to magic, available from the specialized magic trade. There are also web sites which offer videos, DVDs and instructional materials. In this sense, there are very few classical illusions left unrevealed, however this does not appear to have diminished the appeal of performances. In addition, magic is a living art, and new illusions are devised with surprising regularity. Sometimes a 'new' illusion will be built on an illusion that is old enough to have become unfamiliar.
Some magicians have taken the controversial position that revealing the methods used in certain works of magic can enhance the appreciation of the audience for cleverness of magic. Penn and Teller frequently perform tricks using transparent props to reveal how it is done, for example, although they almost always include additional unexplained effects at the end that are made even more astonishing by the revealing props being used.
Often what seems to be a revelation of a magical secret is merely another form of misdirection. For instance, a magician may explain to an audience member that the linking rings "have a hole in them" and hand the volunteer two unlinked rings, which the volunteer finds to have become linked as soon as he handles them. At this point the magician may shove his arm through the ring ('the hole in the ring'), proclaiming: "See? Once you know that every ring has a hole, it's easy!"
