Focus Description:

The magician hands the viewer three large paper rings, each made by gluing the ends of a long paper strip together. The viewer cuts the first ring along the middle of the ribbon with scissors until they return to the starting point, resulting in two separate rings. Cutting the second ring in the same way, he gets, to his surprise, not two rings, but one, which is twice as long as the original one. Finally, cutting the third, he again gets a startling result: two rings interlocked with each other.

The result of this trick depends on how the ends of the tape were closed before gluing. Our first ring was obtained by simply connecting the ends of the tape without twisting. The second ring (called a Möbius strip) is obtained by joining the ends of a strip twisted once through 180°. One of the most curious properties of this surface, which has only one side and one edge, is that by cutting it along the middle, we get a large ring, but if you cut it not in the middle, but at a distance of one third of the width from the edge, then you get two rings: one large and a small one linked to it. The third ring was obtained by cutting the tape, the ends of which were twisted twice before gluing, that is, by 360 °.

In another version of the trick, the ring is cut into two separate rings, one of which, when cut in the middle, also turns into two separate rings, and the other into one large one. The original method of making a ring for such a trick is shown in fig. 4, and its improvement is shown in Fig. 5. Some kind of quick-drying glue is used to glue the ends.

Focus Paper Rings

The method of preparing a paper tape, in which, after two cuts, a chain of three interlocked rings is obtained, is shown in Fig. 6.

Focus Paper Rings

If the ring is made as shown in Fig. 7, then after the first tearing (cutting) a large ring will be obtained, the size of which is twice as large as the original one, and the second tearing will give a ring four times longer than the original one.

Another option is shown in Fig. 8, the first tearing gives one large ring, and the second - two linked:

Ris.8

You can think of other combinations. For example, after breaking the ring shown in Fig. 9, two separate rings are obtained. Breaking one of them gives a chain of three rings, tearing the other - one big ring. This last ring can be broken again, and an even larger ring will be obtained:

Ris.9

If you pass the three times twisted ribbon through the ring, glue the ends, and then cut or tear along the middle, you get one large ring with a knot tied around the ring.

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 ... >>

Dry cleaning can be dangerous 03.12.2011

Fifteen-year-old schoolgirl Alexa Danzler from the city of Arlington (USA) became interested in the problem: do the dangerous chemicals used in this process remain on clothes after dry cleaning?

She sewed squares of wool, silk, cotton, and polyester into the lining of seven identical men's jackets and took the jackets to the dry cleaners. Some jackets have been dry-cleaned up to six times. Then the schoolgirl turned to the local university with a request to do a chemical analysis of the experimental shreds.

It turned out that they still contained the solvent perchlorethylene, which is used in most dry cleaners and is known to cause cancer and neurological diseases. Moreover, this chemical is the greater, the more often the fabric was cleaned, and especially it accumulates in wool.

Although all countries have standards for the permissible levels of perchlorethylene vapor in industrial premises, no one has yet thought about its residues in clothing.
