Newspaper shirt. The Secret of Focus

Directory / Spectacular tricks and their clues

Focus Description:

Fold the newspaper vertically with the edges facing inward. Fold it in half horizontally. If you now bend the ends outward, you get a newspaper shirt.

Show me the empty basin. Pour water into it and put in a shirt folded from newspaper. If you now pour washing powder into water and wash the newspaper, it will turn into a real shirt.

Focus secret:

What's the secret? Washing powder boxes have no bottom. It is divided in half. In the upper part there is powder, and in the lower part there is a real shirt carefully folded into a bundle.

Focus Newspaper shirt

Holding the shirt, pour the powder into the basin. Immediately, under the cover of the edge of the newspaper, drop the bundle into the basin. When “washing” the newspaper, slowly straighten the shirt. Hide pieces of wet newspaper in a real shirt, and take it out of the basin, wring it out and show it.

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 ... >>

Athletes are harmed by any blows to the head 20.01.2018

Researchers from several American laboratories in experiments on mice have shown that chronic traumatic encephalopathy (CTE) is provoked not only by strong blows to the head, causing a concussion, but also by other traumatic effects. The main risk factor is the frequency of injury: if the head is hit regularly, the likelihood of CTE increases regardless of the strength of the blows. These results explain why helmets and other head protection measures in athletes are often ineffective in preventing chronic traumatic encephalopathy.

The experiments were carried out on mice. Animals were subjected either to a shock wave or to a blow to the head with a blunt object. After that, we recorded what changes occurred in the behavior of mice and whether it is possible to say that specific rodents have a concussion (it is detected by a number of behavioral signs). A similar effect was repeated several times, that is, if at first the mouse was "beaten" with a shock wave, then in subsequent experiments the same method was used. Changes in the state of the nervous tissue of rodents were studied on sections passing through various parts of their brain.

Signs of concussion were observed only in those rodents that were subjected to mechanical blows to the head. At the same time, chronic traumatic encephalopathy developed in those who were exposed to the shock wave, and in those who were beaten on the head in the "usual" way. This means that in some cases CTE does not manifest itself in any way, and its development is not necessarily associated with concussion. Thus, many athletes who have never been diagnosed with a concussion may be affected by chronic traumatic encephalopathy. Those at risk are primarily those who are most often hit on the head - boxers, as well as rugby and American football players.

Chronic traumatic encephalopathy is an organic brain lesion caused by head trauma. With it, attention, memory are disturbed, and mood often also suffers. In CTE, nerve cells often accumulate amyloid proteins that cause Alzheimer's disease. In any case, this pathology causes trouble for the patient: at the level of behavior, it often manifests itself as depression and suicidal thoughts, memory impairment, etc. is observed.

The researchers hope their findings will lead the relevant sports federations to reconsider the eligibility requirements for athletes who have had head injuries to play or practice, and this will help reduce the prevalence of CTE.
