Making a Coin Disappear 

 at a Word of Command 



HERE is a clever method of causing a 

 coin to disappear. The apparatus 

 required is very simple and easy to make, 

 and the effect is satisfactorily perplexing. 



The manner of disposing of the inner cup with 

 the coin. Its hook catches on the coat sleeve 



The performer extends his left hand which 

 holds a small circular metal cup, or box, 

 painted some bright color on the outside 

 and jet black on the inside. Transferring 

 the cup to his right hand he asks a spectator 

 to drop a coin into the box while it is thus 

 extended. The left arm and hand are now 

 outstretched and shown empty, and with 

 the right hand which still holds the cup, the 

 left arm sleeve is pulled back and the metal 

 cup containing the coin is placed in the 

 palm of the left hand as in the illustration. 

 At a command the coin vanishes and the 

 box can be closel>- examined b>' the 

 audience. 



The trick is accomplished as follows: 

 The cup contains a smaller cup which fits 

 in it very easily and this smaller cup is 

 lined and covered on the Outside with 

 cotton dyed a jet black to match the inside 

 of the metal cup into which it fits. A small 

 wire is attached to one side of it and extends 

 upward, terminating in a hook. This 

 smaller cup, which is only half as high as 

 the one into which it fits, is slipped into the 



larger cup, the black wire hook which 

 extends over the edge being kept covered 

 with the thumb. When the coin is dropped 

 into the box it falls into the inner cup. This 

 is done while the box is held in the right 

 hand. When pulling back the sleeves of 

 the left arm this hook is allowed to catch 

 into the cloth of the coat, which auto- 

 matically pulls out the inner cup containing 

 the coin. The covering of black cotton on 

 this inner "fake" deadens all noise. 



Any boy can do this stunt after five 

 minutes' practice and will find it baflfling, 

 although it is one of the professional 

 magician's most cherished little secrets. It 

 is needless to say that the performer must 

 stand slightly to one side so that no one can 

 see the hidden "fake" when it catches 

 on the coat sleeve. 



Photographing Magnetic Field Lines 

 Without a Negative 



THE method described will produce 

 perfect photographs, if the directions 

 are followed carefully. In a dark room, 

 lighted only with a ruby light, place a 



The lines of force taken on by the iron 

 filings when placed over the magnetic field 



magnet beneath a non-magnetic surface. 

 Place on this surface a piece of developing 

 paper with the sensitized surface up, and 

 on this sprinkle iron filings in a thin layer.
