Directory / Spectacular tricks and their clues

Focus Description:

The performer speaks of the accuracy of mathematics and adds that this science, in illusion, begins to suffer from errors. Ask the audience:

What is five plus five?

Viewers respond:

- Ten.

"Good," the magician approves. - We'll check it out now. He takes ten five-kopeck coins and a pouch from the table. All this is subject to inspection. He asks two spectators to come to his aid and hands ten coins to one, and a pouch to the other.

Taking a small tray from the table, he asks to put five coins on it, counting one by one. The viewer puts down and counts out loud. The illusionist asks another assistant to open the pouch.

You're asking:

- How many coins are on the tray?

- Five.

Pour them into a pouch (Fig. 34).

Focus 5 + 5 is not always 10

- Okay, five. - Ask to tighten the pouch and hold it by the laces.

- How many coins are in the pouch? Five? Great, you say. - Put the remaining five coins on my tray and count.

The spectator aloud counts and puts the coins,

- Open the pouch, - you continue and pour the remaining five coins into the pouch from the tray. - Now close. You put down five, then five more coins. Five plus five - how much" will it be?

Viewers respond:

- Ten.

- Ten? Now let's check.

The performer, holding the tray with both hands, asks the viewer to take out one coin from the pouch and, counting aloud, put them on the tray. The viewer counts, but the coins are not ten, but eighteen.

- You see, what focus mathematics is. It turns out that five plus five is not ten, but eighteen.

Props:

Copper five-kopeck coins, twenty pieces ..

Pouch on hold with lining (Fig. 45).

Tray with secret passages for coins.

Focus secret:

The whole secret of this simple number is in the tray shown in fig. 46. It has a double bottom and is painted with oil paints; the pattern is chosen so that it well masks the holes for the exit of coins.

Focus 5 + 5 is not always 10
Fig. 46

Between the real and the false bottom, the sides are soldered with a height of a hundredth, a little more than the thickness of a five-kopeck coin and a little wider, so that the coins can easily enter and move along this course. On each side of the tray there is a hole through which the coppers are loaded into the tray. Its size is approximately 13x25 cm.

The dotted line in the figure shows moves - places for coins. The device is so simple that it does not require explanation. We add that when working, the tray should be held by the short sides so that the audience does not find holes.

To "charge" the tray with coins, coppers are lowered into the hole. Standing up, one side is charged first, then, covering the hole with a finger, the tray is turned over and its other side is charged. It is necessary to pour coins from the tray with a sharp movement so that the coins from the course fall into the pouch at the same time as the coppers on the tray.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food.
