Comments on the article

For experience you need:

transparent plastic bottle;
large bowl or deep tray;
water;
coins;
a strip of paper;
pencil;
ruler;
duct tape.

Under pressure

1. Fill the bowl and bottle halfway with water.

2. Draw a scale on a strip of paper and tape it to the bottle.

3. Put two or three small stacks of coins on the bottom of the bowl so that you can set the neck of the bottle on them. Thanks to this, the neck of the bottle will not rest against the bottom, and water will be able to freely flow out of the bottle and flow into it.

4. Plug the neck of the bottle with your thumb and carefully place the bottle upside down on the coins.

Your water barometer will allow you to observe changes in atmospheric pressure. As the pressure rises, the water level in the bottle will rise. When the pressure drops, the water level will drop.

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. ... >>

Knotted bicycle 09.02.2011

Folding bikes are not new, but young English designer Kevin Scott came up with a new approach that also solves the problem of bike theft.

The two frame elements in its design are made of short lengths of pipes strung on a strong, taut cable. When driving, such a frame works like a normal one. In the parking lot, the cyclist loosens the cables, wraps his car around any pole, and padlocks both wheels. To return the bike to working condition, it is necessary to tighten the cables again, for which there is a miniature winch on the frame.

With an average of 52 bikes stolen daily in London alone, Scott's model is likely to be in demand.
