EFFECTIVE FOCUSES AND THEIR CLUES Magic clock. Focus secret
Directory / Spectacular tricks and their clues Focus Description: On a stand standing on three legs, they carry out a large quadrangular glass dial with a nickel-plated arrow. The size of the dial is approximately 40x40 cm. The arrow is 30-35 cm long. The magician removes the arrow, which hung on a thin axis pin, and, taking it in his left hand, right, removes the dial from the tripod. He carries all this into the auditorium and shows it to the audience. Viewers see that a pin is inserted in the center of the dial and there are no other devices. On the dial are drawn numbers from 1 to 12, meaning hours. Returning to the stage, the performer hangs the dial on a tripod and talks about the "magic" properties of this watch. Then he hangs the arrow on the axis of the dial and, quickly twisting it, moves away from the dial. Standing behind the dial, he puts his finger on the number "7", the hand, slowing down, stops at seven o'clock (Fig. 145).
The performer removes the arrow and, quickly showing it, hangs it again on the axis; spinning it so that it begins to rotate, he puts his finger on the back of the dial to the number "5", the hand, spinning, stops at five o'clock. The performer says: the audience is probably convinced that some devices have been made here in advance that stop the arrow in the desired position. To make sure this assumption is wrong, he asks the audience to call any hour. Spectators call (for example, 6). The illusionist hangs the arrow on the axis and, moving three steps to the side, shows from afar with his hand where the arrow should stop. The arrow freezes in the designated place. This is repeated one or two more times. Then the artist removes the arrow and invites one of the spectators to the stage from the audience. She calls a certain time, let's say 4. The performer gives the arrow to the spectator and asks to put it on the axis and spin it better. The spectator fulfills the request, and the arrow, slowing down, stops at four. At this time, the assistant gives the performer a small closed case. The lid is opened, and the audience sees that inside there is not a large dial with an arrow attached to it. Having closed the lid of the case, the performer hands it to the spectator and asks her to put some hour on the dial without showing it to him, and then close the case with a lid. When all this is done, the magician takes the case and hands it to one of the spectators whom he has just called on the stage. The viewer holds a closed case on his outstretched hand (Fig. 146). The performer passes the arrow to the spectator, asks to hang it on the axle and spin it. While the hand is spinning, the performer asks the spectator what hour she put the hand in the case. The spectator says (for example, 12). The performer asks to open the case and show it to the audience. Everyone sees on the dial in the case "12". After that, the stopped arrow also shows 12.
After thanking both assistants from the audience, the performer asks them to take their places. An assistant with a case goes into the audience and asks someone to set any hour without showing it to anyone. The assistant then passes the closed case to another spectator; at the same time, the performer puts the arrow and turns it; when the arrow stops at some number (let's say 6), the performer asks the viewer to open the case and show it to everyone. Everyone can see that on the dial in the case, the hand also stands at six o'clock. At this time, the assistant, taking a plate from the table, an opaque glass (like for shaving) and a pair of dice with points drawn on them, go to the audience. The performer, having removed the arrow, holds it in his hands. The assistant allows one of the spectators to inspect the cubes with a request to put them in a glass, you throw them on a plate, immediately covering them with a glass. While this is being done, the performer, putting the arrow on the axis, twists it. Spinning, the hand stops at ten. The performer asks the viewer to raise a glass. When the glass is removed, everyone sees ten points rolled on the dice. This is where the number ends. The assistant takes the clock backstage, and the illusionist proceeds to the next trick. This number is combined by us from several tricks. For the manufacture of equipment, careful, painstaking and rather difficult work will be required. Props: Large glass dial. The arrow for the dial with a secret. Case with a dial and an arrow with a secret. Small plastic bowl and glass. Two dice. The dial is best made from plexiglass. The size is approximately 40x40 or 50x50 cm. Note that the latter will be much more effective for the audience. We advise you not to make a round disk, it is easier to make a square one. On the dial, as on a clock, the numbers from 1 to 12 are written. Minutes do not need to be marked. A hole with a diameter of 3 mm is drilled in the center. On fig. 185,1 shows a pin that is inserted into this hole and serves as the axis for the arrow. The total length of the pin is 5 cm, and the thickness of the axis is 1 mm. At the end of the pin there is a thickening of 3 mm with a threaded thread, onto which nuts are screwed to fasten the pin in the dial. Along the upper edge, in the corners, two holes are also drilled in the glass. A cord or a very thin metal chain is passed through them to hang the dial on a stand.
Any stand can be used. A nickel-plated music stand with grooves inserted into it for the dial is suitable. Hand made of copper 1 mm thick, nickel-plated, 35-45 cm long, depending on the size of the dial. On fig. 185,2 shows a general view of such an arrow, and in fig. 185,5 is her profile. The arrow can be of any pattern, but in the middle it must certainly have the shape of a circle with a diameter of 3-4 cm. Along the edges of this circle, twelve holes with a diameter of 1-2 mm are evenly drilled at an equal distance from each other. They are arranged according to the twelve digits on the dial (Fig. 185,4). Two covers A and G are placed on top of them (Fig. 185,5). Cover A is made with screw B, which is passed through a hole in the circle. A circle C is put on the screw B from the opposite side with a small pin attached to it on a spring, which, turning together with the circle, will alternately enter the twelve holes of the circle of the arrow. The pin protrudes from the spring just enough to allow it to easily slide in and out of the hole in the wheel as it turns. On the circle, a small lead weight is fixed on the opposite side of the pin. He will drag down that end of the circle to which the pin is facing (Fig. 185, 6); here E is a pin and W is a weight. The circle is attached to the cap G, and the entire system (see Fig. 185, 5) is put on on both sides of the arrow, regulated and strengthened with the nut D. With the same success, the circle B can be fixedly fixed on the axis of the cap A, so that the pin points outward. Put an arrow on it first, then cap G and secure it with nut D. To know where the pin on the cap G with which it is fastened is facing, make a small, barely noticeable notch. It will always indicate the hour you need. You can even, without looking at the hand, put it on the right hour. To do this, you only need to know at what hour the pin was. Now, if you rotate it, it will move, making light blows when entering the holes. By counting these clicks, you can determine at what hour the hand will be set. To set the arrow to the desired hour, it is taken in the left hand, and the cap with the pin is moved with the right hand, counting the strokes or imperceptibly looking at the wheelhouse. My arrow model did not have a spring with a pin. Its device is much simpler and more practical. On a copper mug 1 mm thick, a recess was knocked out with a core, on the reverse side a protrusion was obtained, which served perfectly instead of a pin, entering the hole on the arrow mug. Case with a dial and an arrow - with a secret. A general view of such clocks is shown in Fig. 186, 1. This is a small case with a lid that locks with a latch. Its size is 12 x 16 cm with a thickness of 2-3 cm. A dial is inserted into the case, in the middle of which a strong small arrow is fixed on the axis. It can be rotated around and set to any hour.
A watch in a case has a secret: no matter what hour the spectators set the hand to, without showing it to the performer and closing the case, the illusionist can instantly tell what position the hand is in. Its axis is soldered tightly to the arrow. She is wearing a small gear from the alarm clock. You need to have two such absolutely identical gears with the same number of teeth (Fig. 186,2). One of them, gear A, is tightly soldered to the axis of the arrow. Another is placed next to it - a large gear, which is strengthened in the plates. This gear B should rotate very easily, another, small gear C is attached to it from the other end and put into their sockets. Previously, a cap from a small screw is attached to the axis of gear B, which protrudes beyond the back cover of the case. The head of the screw is sawn at an angle in the form of an arrow (Fig. 186,5). Now, if you start to rotate the arrow, then gear A will also rotate with it. It will engage with gear B, which will turn as many teeth as A turns. Gear B, rotating, will also turn gear C with the head of the screw by the other side of the case. So that this head does not protrude and is not conspicuous, you must place exactly the same screw heads in all other corners. Install the rotating screw with a narrow cut so that it indicates the position of the hour hand. When the arrow is on the number "12", then the head should be at an acute angle facing up; when the arrow is on the number "6", the head is facing down. But for the rest of the time, the head will show the opposite (for example, it will display 3 hours as 9). On fig. 186,3 shows the location of the numbers relative to the slot of the screw. It is necessary to practice very well with the watch, so that instantly, imperceptibly looking at the screw on the back of the case, you can accurately name the hour at which the hand is set. Imagine that you see an arrow through the bottom of the box. This is the whole simple mechanics of this watch. The most important thing is to make a rotating head that would be no different from the heads of the other three screws. From adjust the rotation of all three gears as best as possible. The arrow must turn very easily, so that the audience does not have any doubts. After one of the spectators puts the arrow and closes the case, do not immediately look at the position of the screw head. Do this when you pick up the case or at another convenient time. After a moment's glance at the head of the screw, immediately look away from it. Play in memory its position and immediately determine the desired hour. Your assistant will have to perform with the case, so you should train him as best as possible. A small plastic plate and the same glass do not need a detailed description. Shaving accessories are suitable for this purpose. Two cubes are easy to make from hard wood or ebonite. On each side of 12 mm, make small indentations with a drill that will indicate glasses. On the whole die, the sum of the opposite sides of the points must always equal seven. For example, if there are two points on one side, then there should be five on the opposite side. Round the corners of the cubes a little. Focus secret: There are many secrets in this trick. The hour hand, as you saw, has a moving weight hidden from the audience. The weight pin moves through the holes. By translating half of the lid, you can easily feel these clicks and you can always count the hour you need. True, it is much easier, when moving the weight, to follow the mark "G" on the hemisphere (see Fig. 185,5). This hole will always show the hour set by the viewer. We should not forget that by turning the hand over and putting it on the axis, you will make the hand show a different hour. Let's explain this with examples. As already mentioned, only the numbers "6" and "12" the arrow will always show the same way on both sides. If you put it at 1 o'clock, and then turn it over to the other side, then the hand will show 11, if you put it at 2 o'clock - 10, at 3 o'clock - 9, at 4 o'clock - 8, at 5 o'clock - 7 and vice versa. Therefore, before rearranging the weight, check if the reverse side of the arrow fits. Let's say your hand just stood at 8, and they tell you the next hour is 4; the easiest way is to turn the arrow on the other side imperceptibly in your hands. This should not be forgotten. Now the secret of the arrow is probably clear to you. We talked about the secret of the case with the dial in detail, talking about its device. It only remains for us to reveal the secret, as the assistant reports the desired figure to the performer. There are several such methods: with the help of "mnemonics", that is, an encrypted conversation, you can convey the desired word in a question or gestures, facial expressions. In our case, only twelve numbers need to be reported. We advise you to choose a combined transmission: words and movements of the body, legs, head, hands. Just don't forget to carefully rehearse all this with your assistant: after all, tell the illusionist the hour set on the dial in the case, and the number of points dropped out to him. You need to immediately show the assistant with conventional signs the number that you have accepted, and he must confirm with some conventional word or signal that the number you have accepted is correct. Since viewers rarely place 12 and 6, it is very easy to indicate 12 by raising the head up straight in front of you, and 6 by lowering it down. Send the rest of the numbers in the way you choose. It will be much more interesting for you to have your own transmission, a cipher that only two people will know - you and the assistant. Before the performance, set the hand to the hour you need in advance (in our case, 7). Then the whole number goes in accordance with the description of the external effect of the focus.
