Focus Description:

You can make snow stars in severe frost.

Focus secret:

Prepare a straw for the experiment, a soapy solution.

When a cloud forms at a very low temperature, instead of raindrops, water vapor condenses into tiny needles of ice; needles stick together, and snow falls to the ground. Snow flakes consist of small crystals arranged in the form of stars of amazing regularity and variety. Each asterisk is divided into three, six, twelve parts, symmetrically arranged around one axis or point.

We don't need to climb into the clouds to see these snow stars form.

It is only necessary to go out of the house in severe frost and blow a soap bubble. Immediately, ice needles will appear in a thin film of water; they will gather before our eyes into wonderful snow stars and flowers.

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.

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 ... >>

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.
