Focus Description:

Place two dice on the table and ask a spectator to point to one of them. When he does this, ask him, pointing to the cube chosen by the viewer and at the same time touching its upper edge with the pad of the index finger, previously moistened with saliva: “This one?”

Then take another die and place it on the top edge of the selected die. Carefully lift the top cube by its sides.

Focus Sticky Cubes

Focus secret:

If a sufficient amount of saliva has transferred to the lower cube, it will stick to the upper one and rise with it.

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. ... >>

carbon dioxide from moist air 30.01.2016

There are different technologies for capturing carbon dioxide without the help of living organisms. For example, if you pass the gases emitted by the pipes of the power plant through a solution of calcium chloride, calcium carbonate will precipitate, which can then be decomposed, returning calcium to circulation, and carbon dioxide sent for processing. Or you can try to collect carbon dioxide with a sorbent, so that then again it is isolated, sent for processing, and the sorbent is returned to business.

Until recently, there was no good sorbent: as a rule, carbon dioxide molecules stick to the same active sites as water molecules, and there is incomparably more moisture in the air than CO2. An international team of researchers has managed to create a sorbent in which moisture and carbon dioxide sit on different active sites. It was named SGU-29 after Korea's Seogang University, where the material took its final form. The basis was crystalline copper silicate.

"The sorbent is the most difficult part of the work. Now it is behind us, and carbon dioxide processing technologies are ahead. In about five years we will finish the work," says research participant Professor Osamu Terasaki from Stockholm University.

However, carbon dioxide must be extracted not only from the emissions of a factory or power plant. In the air of residential and office premises, an excess of carbon dioxide is also undesirable. It would be interesting to know whether the new sorbent can be useful here as well.
