Glasses in cylinders. Focus Secret
Directory / Spectacular tricks and their clues
Comments on the article
Focus Description:
On the table are two glasses of transparent glass and one of red, as well as three cylinder cases. Turn the glasses upside down so they line up. Cover the top with cases.
Then knock with the "magic wand" and, lifting the cases one at a time, show that the red glass was on the edge, and has now moved under the middle cylinder. Tap again with the "magic wand" - and the red glass will move under the cylinder from the other side. Then she will return to the place where she was at the very beginning.
Secret of focus
Three cylinder-cases made of cardboard, two transparent and one red glasses are used, as well as three secret inserts, which are transparent cylinders that are freely put on the glass from above - two red and one transparent.
Cylinder "a" has a hole for a finger at the back, in the wall. To show that there is no red glass under this cylinder, but a transparent one, you need to insert your index finger into the hole and, raising the cylinder, lift the glass up with it, propping your finger under the leg of the glass. Only the transparent insert will come out.
To make a red glass appear under the cylinder "b", the cylinder simply rises. The red glass insert will remain on top of the transparent glass, and it will seem that it is only a red glass.
To make a transparent glass appear, you need to squeeze the cylinder on the sides with your fingers and lift it together with the insert. Only a transparent glass will appear outside. Cylinder "b" works in the same way.

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 ... >>
Random news from the Archive Living organism found without air
28.02.2020
Israeli scientists have discovered a multicellular living organism that does not need air to live. A parasite with the Latin name Henneguya salminicola, which was found in salmon, has become a unique animal.
Scientists were able to discover during the study that the parasite does not have a mitochondrial genome. That is, the air for him is not the basis of existence.
At the same time, it is noted that previously organisms were already known that could survive with a limited amount of oxygen, but this type of parasite is the first multicellular creature that can completely do without air.
The researchers speculate that mitochondria were lost by the Henneguya salminicola parasite during evolution as it needed to adapt to its environment.
According to scientists, such a discovery could change the understanding of life not only on Earth, but also in space.
