Try to get a piece of camphor. She has such a property: if you put a piece on the water, then the particles of camphor will begin to separate with great speed. Understand? After all, this is suitable for a jet engine! It is only necessary to arrange so that the particles can only go out in one direction.

To do this, make a small boat out of aluminum foil (chocolate and expensive varieties of sweets are wrapped in it). Insert a piece of camphor into the slot in the stern of the boat. Now the boat can run non-stop for hours on the surface of the water in the basin!

jet boat

The jet engine of our boat is so simple that you can't imagine it being simpler. However, he may refuse to work. When I was still a very small boy, I was once presented with such a boat. Only not home-made, from foil, but purchased, celluloid. The boat was very beautiful, but - alas! - he did not even think of moving, although a decent piece of camphor was attached to him.

Only much later did I find out what was the matter. It turns out that this beautiful experience does not tolerate the slightest trace of fat. They should not be on the boat or on the surface of the water. Therefore, taking up the manufacture of the boat, wash your hands thoroughly. Wipe the finished boat with a cotton swab dipped in ether. And wash the basin thoroughly with hot water and soda or washing powder before the experiment!

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. ... >>

Global warming destroys the digestive system 27.08.2023

Global warming has not only obvious environmental consequences, but also impacts on human health. A recent study by German experts uncovers worrying trends regarding the impact of climate change on the human digestive system.

It turned out that an increase in ambient temperature can become a split in the usual balance of health. For the human body, the optimum temperature is approximately 40 ° C - above this point, the functioning of the organs is disrupted. Scientists paid special attention to the effects of heat on the digestive system, revealing that hot weather promotes the growth of bacteria that cause foodborne infections.

Temperature changes affect the spread of dangerous bacteria such as Salmnolella, Vibrio, Campylobacter, as well as Giardia and Cryptosporidium parasites. Now most cases of salmonellosis in Europe are registered during the holidays. However, long and warm summers increase the potential for transmission of foodborne pathogens.

Global warming affects many processes, including the emergence of toxic algae and bacteria in aquatic ecosystems. These toxins can end up in food and drinking water. Agriculture, faced with water shortages, may be forced to use treated wastewater, which creates the risk of contamination of food with pathogens.

Scientists strongly recommend that you follow the rules of hygiene regardless of the time of year: wash your hands before cooking, store food properly (meat should be stored separately); use different tools and cutting boards for processing vegetables and meat, which will help reduce the risk of infection with pathogens.
