Focus Description:

The coin appears under any card.

Focus secret:

Prepare two identical coins and wax both on one side. Ask the audience for a third coin and secretly stick it on one of the waxed ones, placing the last one waxed side up on the table.

Let someone draw two cards from an ordinary deck. Take these cards in your left hand and, shifting them to your right, press the second waxed coin to the center of the lower one, to which it will stick.

Place this card (which we will call A) on the table, at a distance of 45 cm from the coin already lying there, and cover this coin with another card B.

Raise both cards A and B slightly off the table to show that the coin is under card A and that there appears to be nothing under card B. When you move them, press lightly on the center A.

Now you can make the coin appear under any card, remembering one thing, that if you wish the coin not to stick, then you must slightly bend the card up while lifting it off the table; if you do not want this, then lift it without bending 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. ... >>

Another innovation is 4K video recording (at up to 30 fps) and a bit rate of 100 Mbps. At 1080p, the frame rate can be increased up to 60 fps. Film Simulation modes can also be applied to video. Supports Clean HDMI video signal and F-Log gamma correction.

The camera uses a hybrid autofocus system with an increased number of points compared to the previous model. In the description of the camera, the manufacturer draws attention to the user settings of the AF-C mode.

In the equipment of the device, one can distinguish an electronic viewfinder of the OLED type with a resolution of 2,36 million dots, which is characterized by a magnification of 0,77x and an inertia of only 0,005 s. The equipment also includes a movable three-inch display, two SD slots, a Wi-Fi module. The body of the X-T2 is made of magnesium alloy and sealed, which ensures protection against dust and moisture. The chamber keeps working capacity at temperatures up to -10 °С.

Camera dimensions - 133 x 92 x 49 mm, weight - 507 g. Without recharging the battery, you can take 340 shots.
