Focus Description:

Take three coins and arrange them in a row on a table covered with a tablecloth. Then cover them with a glass turned upside down so that its edges rest on two coins, and the third is in the center.

Invite the audience to get a coin from under the glass without touching the glass.

If their attempts are unsuccessful, use your index finger to scrape the table around the glass yourself. And the coin will crawl out from under the glass.

Focus Creeping Coin

Focus secret:

By scraping the tablecloth, you pull the fabric out: it slides across the table and sets the coin in motion, which gradually crawls out from under the glass. The coins on which the glass rests must be somewhat thicker than the third, so that it can pass unhindered under the glass.

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

Eyes to eyes 05.01.2017

Scientists from Kyoto University (Japan) Shogo Kajimura (Shogo Kajimura) and Michio Nomura (Michio Nomura) have shown that eye contact overloads the brain during communication, which is why it is so difficult for us to look into the eyes of the interlocutor for a long time. An article about the study was published in the journal Cognition, the results are presented in a press release.

The experiment, in which 26 volunteers took part, consisted of a simple game of association: a person was called a word (noun) and asked to immediately give an answer - a verb. For example, "ball" - "throw". At the same time, the tasks were of varying complexity: it was more difficult to find an answer to some words than to others. At the same time, the subjects interacted with the face on the computer, and it set the tasks.

The researchers compared how long it took the volunteers to respond to the tendency to look away, breaking eye contact. It turned out that difficult words predictably caused more difficulty, but the time was reduced if the person averted their eyes.

The authors of the work conclude that the dual task of maintaining eye contact and coming up with an association is too difficult for the brain. As a result, he tends to "save" on one task, less important.

Each of us can notice this effect on ourselves, for example, remembering ourselves in the exam. The more complex mental operation we perform, the more likely we begin to involuntarily look away and look away, and not at the person.
