Focus Description:

Pour sparkling water into a glass. Take a small button and dip it into the glass. The button will be at the bottom.

She will obediently let go.

Focus Obedient Button

Focus secret:

Why is this happening? When a button is at the bottom of a glass, carbon dioxide bubbles gather around it. When there are quite a few of them, they will raise a button. After that, the bubbles will disappear, and the button will again be released due to its own weight. This up and down movement continues as long as carbon dioxide is released.

Pre-practice, calculate the time, how long you need to wait before telling the button "up" or "down".

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. ... >>

New digital camera reference design announced 24.03.2007

Texas Instruments Corporation, a leading manufacturer of semiconductor products, announced the development of a new reference design based on the DaVinci image processor that increases the performance of digital compact cameras "to the level of SLRs."

The main advantage of the new idea is to increase the speed of serial shooting of digital compacts up to 5 frames per second. Recall that even entry-level and mid-level digital SLR cameras cannot boast of such speed, for example, the rate of fire of such models as the Canon EOS 400D, Nikon D80 and Sony DSLR-A100 is "only" 3 frames per second.

The reference design includes Micron Technology's new 8-megapixel CMOS sensor and a proprietary high-definition (HD) video hardware codec capable of "bringing HD video to sub-$99 models."

Moreover, according to the official press release, the new image stabilization system, coupled with the high performance of the DaVinci processor, reaching 10 megapixels per second, will enable manufacturers of digital cameras to set the sensitivity of new models up to ISO 10000.
