Focus Description:

In your hands you have a small blue handkerchief. Show the audience your left hand, then clench your palm into a fist and slowly tuck the handkerchief into it with your right. Then, on the other side of the fist, you pull out a handkerchief, but ... red. Open your fist - it is empty.

Focus Instead of a blue scarf - red

Focus secret:

The secret of the trick is in the little tube. You can make it from thin tin or plastic. The length of the tube is about 50 mm. Choose the diameter so that the tube fits freely on your thumb. In the center of it around the entire diameter, make several small holes. They are needed to sew a small bag of cloth into the tube. So that the tube is not visible on your finger from a short distance, paint it in flesh color.

Before demonstrating the trick, put a red handkerchief in the bag, and put the tube on the thumb of your right hand. Take a blue handkerchief in the same hand. Show the audience the left hand - there is nothing in it. And then, disguising your hand with a blue handkerchief, quickly remove the tube and leave it in your left hand together with the red handkerchief. Now it is clear that you are tucking the blue handkerchief into the tube, and he, pushing out the red one, takes its place. As soon as the red handkerchief appears from your hand, put the straw back on your finger, unfold it and show it to the audience from both sides.

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 ... >>

Bank card will lose its magnetic stripe 17.02.2014

The US banking system plans to replace obsolete and technically vulnerable magnetic stripe plastic credit cards, which are now used by residents of the country for cashless payments, with a new type of card. According to the Wall Street Journal, this modernization will be carried out everywhere in October 2015.

New cards will necessarily acquire chip-and-PIN technology, which has been used by banking structures in the rest of the world for several years. No matter how surprising it may seem, a magnetic stripe card is still common in the United States, despite the huge number of fraudulent counterfeiting and illegal withdrawal of amounts from the owners' accounts without their knowledge and consent. There will be no more magnetic stripes, no more black line reading.

Americans who have traveled extensively in Europe, especially in the last few years, have noted that the credit card system in the United States is seen even by them as too old-fashioned and behind the modern trends in this area in comparison with their European counterparts. Often, tourists may experience some difficulties with their "credit cards" while abroad, as in Europe some time ago they abandoned the magnetic stripe due to too high statistics for hacking such cards. However, credit and debit cards, which are still in use for cashless payments in the United States, according to experts, are technically behind the rest of the world by 10 years.

The new type of plastic cards will have a microchip instead of a magnetic stripe and will require a PIN code from the owner when performing the payment procedure. Such a plastic protection system has a number of advantages and is much safer for several reasons. Firstly, the mandatory request for a PIN code will prevent erroneous or deliberate debiting of the amount, for example, by service personnel who make a payment using your card. In a more advanced version with a chip-and-PIN system, you are required to provide a terminal into which you insert a plastic card and immediately enter the "pin code", instead of passing the card into the wrong hands without asking for a "security code". This will eliminate both the factor of the use of your funds by personnel in a dishonorable way, and will protect you from the modifications of terminals that are common today, which easily copy data from a magnetic stripe.

According to recent estimates, hackers managed to steal 70 million credit card numbers from cashless transactions during the peak shopping period from Thanksgiving to Christmas Eve. Attackers "modernized" terminals for receiving classic plastic cards with a magnetic stripe and copied information from it, which allowed them to pay in the future with the help of other people's funds. With a chip-and-PIN system, this operation will be much more difficult. At least, in order to "copy" the chip and find out the owner's password, much more effort and skill, as well as technical devices, will be required. If a system with a chip and a mandatory password cannot completely protect card users from fraud, then it will at least significantly affect the statistics of such thefts.

In addition, the magnetic strip has become too "tidbit" for hackers, as it can be hacked even by not very highly skilled villains. In France, there has been an 80% reduction in credit card fraud with the transition to a chip-and-PIN system, although these statistics are rather vague due to the unofficial source of their original publication.

As for the CIS countries, here, so far, crimes with bank cards have not reached such proportions as in Europe and the United States. Therefore, it is unlikely that any qualitative changes in this direction are expected in the near future. In addition, the culture of non-cash payment in our country is not as well developed as abroad. Therefore, outside of large cities, you may encounter the problem of both cashing out "plastic" and paying with it for services rendered and goods purchased.
