How to balance a plate on a needle point? Of course, you will immediately realize that for this you need to pick up something heavier than a plate. In our experience, four forks are taken. Only they must be steel; aluminum is too light.

Cut two corks lengthwise. If you don’t have such corks, you can cut two pieces of carrot. Insert a fork into each of the four halves so that the angle between the cut plane and the fork is slightly less than a straight one.

Place forks with corks along the edge of the plate at equal distances from one another. For greater stability, the tines of the forks should touch the edge of the plate.

Top plate!

Now the plate can be balanced on the tip of a needle inserted into the cork. It seems to the eye that this is impossible - and yet the plate is worth it! It can even be made to spin if you spin it gently enough. And it will spin for a long time. After all, the friction between the tip of the needle and the plate is small.

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. ... >>
