Focus Description:

Have someone spin a coin on a table not covered by a tablecloth. While you are standing with your back turned away, immediately tell when the coin stops, which side it is up - heads or tails.

Focus secret:

On one side of the coin (say, on the tails), a small notch is made at the edge so that a small piece of metal sticks out of it in this place.

Focus Spinning Coin

When such a coin is twirled, listen to how it falls. If the notch is up, then it will ring like an ordinary coin - with a long, prolonged sound "rrrr", and it will gradually weaken until it stops altogether; if it falls with the notch down, then the friction of the metal protrusion on the table will halve the time of the sound of the gradually fading sound. This difference in sound is not too noticeable to attract the attention of those present, but is quite understandable to attentive ears.

Therefore, if you made a notch on the side of the tails and the coin, falling, sounds weaker, then tails fell out, if it is stronger - heads.

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 ... >>
