Focus Glass of water from pocket

An ordinary balloon was put on the top of the glass filled with water, so the water did not spill. With your hand in your side pocket, remove the ball from the glass and leave it there. Take out a glass of water and show it to the audience.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Tape without glue 06.09.2003

The University of Manchester (England) has created adhesive tape without glue. True, so far only a small piece of one square centimeter has been obtained.

The developers took advantage of the recently revealed secret of the gecko. This small lizard runs briskly along vertical surfaces, including glass. It was recently discovered that the legs of the gecko are covered with the finest hairs, which, in contact with any surface, are attracted to it simply due to intermolecular forces. Each hair provides only a very slight attraction, but there are many billions of such hairs. By shifting the sole so that the hairs form an acute angle with the surface, the gecko disengages the foot from the surface.

Using nanotechnology methods, the researchers were able to apply hairs 2 microns long and 0,2 microns thick to a flexible polymer film, just like a natural sample. There are about a hundred million of them per square centimeter.

It is estimated that if you make a glove with such a coating, a person can hang on the ceiling or wall on one hand wearing such a glove. But the mass production of such a film is not yet planned: the process is too complicated. And it is not clear how long the micro-hairs will last - in a gecko they grow as they are erased.
