Focus Description:

Three different objects are placed on the table in a row, and the places they occupy (not the objects themselves, but only the places) are indicated by the numbers 1, 2 and 3. The magician turns his back to the audience, and one of those present begins to swap objects in pairs, naming this is just the numbers corresponding to the places. So, for example, rearranging the objects in the first and third places, he says aloud "one and three."

Thus, the viewer can move the objects as many times as he likes, but be sure to call the appropriate numbers. When he finally gets tired of this occupation, he thinks of some object and swaps two other objects, without saying anything to the demonstrator. Then he again begins to rearrange objects in pairs in an arbitrary way, but again naming the corresponding numbers aloud.

So the viewer can continue until he gets bored. In the end, the magician turns to the table and immediately points out the intended object.

Focus secret:

Standing with your back to the table, you imperceptibly for the viewer use some hand as a counting device. Let three fingers (for example, index, middle and ring fingers) represent the numbers 1, 2 and 3. Before turning away from objects, notice the position of one of them. Let's say that you took a ring, a pencil and a coin to show the trick and the ring takes position 1 Then touch with your thumb the finger to which you attributed the number 1. As the viewer announces aloud your permutations, you should move your thumb over the fingers indicating the numbers, while watching only the position of the ring. So, if the first permutation included 1 and 3, you move your thumb to finger number 3. If the permutation included 2 and 3, without affecting the rings, then you do nothing, leaving the thumb in the same place.

After the spectator has conceived the object and made a shift unknown to you of the other two, he again begins to call aloud the numbers denoting the permutations. At the same time, you continue to follow the position of the ring, as if it had not changed as a result of a movement unknown to you.

At the conclusion of all permutation operations, your thumb will stop at one finger. Let's say this finger is number 2. Look at the second place on the table. If there is a ring there, you immediately determine that it was the ring that was intended, because its position has not changed as a result of a movement unknown to you.

If the ring is not where your thumb is pointing, then look at the other two objects (the ring and something else). This other object (not the ring) will be intended.

This method is amazingly simple and it is easy to guess why it works. In fact, we are dealing here with a task of elementary logic, where the fingers play the role of the simplest logical machine.

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 Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Charging implants with ultrasound 16.03.2020

Researchers at the King Abdullah University of Science and Technology have come up with an idea for how implantable surgical devices and stimulators can be remotely charged using a special hydrogel.

The system proposed by scientists is based on a new type of biocompatible hydrogel that contains a lot of water, that is, it can safely stretch and bend with the body, as well as conduct electricity.

The researchers mixed polyvinyl alcohol with tiny pieces of MXene, a two-dimensional material made from transition metal carbides, nitrides, or carbonitrides. The result is the so-called M-Gel, which is able to generate electricity under pressure, which forces charged ions to move through the water in the gel.

Scientists have studied the effectiveness of exposure to ultrasound gel in a series of experiments. They placed the device a few centimeters inside a piece of beef and turned on several ultrasound devices in turn, which are used in medical clinics and laboratories. As a result, they were able to quickly charge the device.

"Like a salt solution makes water conduct electricity, so we used MXene nanoflakes to create a hydrogel. We were surprised to find that the resulting material could generate electrical energy when exposed to ultrasonic waves," lead author Lee Kang-hyuk said.
