Focus Description:
The box opens on its own.
Focus secret:
Turn the matchbox upside down. Make two holes in the center of the lid - close to each other. Through these holes, connect both parts of the box with an elastic band and, pulling it, tie it with a ring.
Open the box. Hold it in your hand, slightly squeezing the edges. If you now release the boxes, then under the action of the rubber band, it will close on its own. You can open it from the opposite side and repeat the trick. You can even throw an open box on the table - it will also close.

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. ... >>
Random news from the Archive Cars go on rails
26.02.2002
The Danish company RUF International presented to the government a project designed to solve the problem of congestion in the transport networks of large cities. The essence of the project is to direct all urban transport, including cars, on rails.
The proposed transport system is a network of monorail roads along which public and private electric vehicles move. Small sections of the way transport overcomes on ordinary roads. Then he enters the rails and combines into a kind of train moving at speeds up to 120 km / h.
It is also planned to automate sections of roads without rails: sensors installed underground form a kind of fairway, so that drivers may not drive their cars at all. Cars for the RUF transport system can be anything, but for driving on rails they must have a V-shaped channel running along the bottom of the body.
The monorail system is intended for large cities, but the authors of the project did not forget about the inhabitants of the suburban area: a hybrid transport with electric and fuel engines is provided.
