Focus Description:

This trick consists in the disappearance of the rabbit, incomprehensible to the audience. In fact, of course, you prepared everything for this in advance - a cardboard box without a bottom, and a lid, and the lid itself, somewhat larger in size than the box, as well as a bag attached to the lid at the corners. The bag during the demonstration of the trick must remain invisible to the audience.

Focus secret:

Before the trick begins, the lid is on the box, and the rabbit sits next to the box. Not far from the box, an assistant stands with his forearms and hands extended forward and horizontally to the floor. Throw a large white handkerchief over his forearms (he does not change the position of his hands).

Sliding the lid off the box so that it, leaning on the box, stood on the table almost vertically - with a plane to the audience. The bag remains inside the box. Lift the rabbit up and put it in the bag (fig. b - in the direction of the arrow). Then, taking the side edges of the lid between both hands, slide the lid onto the box with a movement towards yourself and towards the box; in this case, the bag with the rabbit must be moved to the near wall of the box (Fig. c). The audience is convinced that the rabbit is inside the box, and this is true.

Then turn the lid on its horizontal plane around the vertical axis (Fig. c - along the arrow), and as a result of this movement, the bag with the rabbit will be already at the far wall of the box (Fig. d).

After that, grasping the near corners of the lid with both hands, lift these corners, which will cause the lid to again turn out to be an unfolded plane on the hall. But you do not stop, but keep moving: tip the lid onto the table by turning around the axis passing through the far edge of the lid (Fig. e - in the direction of the arrow), as a result of which the other side of the lid will also open to the eyes of the audience (Fig. e - in the direction of the arrow), which you hold flat to the audience. Together with the lid going up, a bag with a rabbit sitting inside it is also pulled out of the box (Fig. g). The audience is convinced that the rabbit is still in the box, but now they are wrong.

Throw the lid on the assistant's outstretched arms so that the bag with the rabbit below the lid is between your assistant's hands - the handkerchief lying on his forearms will hide the bag with the rabbit - and triumphantly lift the box up - without a bottom and a lid. It is empty - the rabbit is gone!

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 ... >>

Music intoxication 18.07.2018

Some people feel drunk at the sound of music, and this is not a metaphor at all - not only music, but generally sounds of a certain frequency make them dizzy, nausea and loss of balance. Such a reaction can also occur to the human voice, to changes in atmospheric pressure, and even to a cough, and it is associated with a congenital pathology of the inner ear called dehiscence of the semicircular canals.

As you know, the inner ear is a system of bone cavities that form the cochlea (the organ of hearing) and the vestibule with the semicircular canals (the organ of balance). Usually, the organ of hearing and the organ of balance are isolated from each other by a bone wall. But in 1929, the biologist Pietro Tullio discovered that the bone between the cochlea and the semicircular canals is sometimes very thin, or there is a hole at all, and this is somehow related to the symptoms of "music drunkenness."

But what exactly happens in the inner ear with pathology when sounds of a certain frequency reach it? Researchers at the University of Utah describe this using the example of a toad fish, whose organs of hearing and balance are similar to those of humans.

The semicircular canals in us and in fish are filled with a special fluid, and when our body somehow moves, somehow changes its position in space, the fluid in the semicircular canals also moves, and its movement is sensed by special cells that send a signal to the brain. In turn, the brain, in turn, tries to coordinate the work of the muscles so as not to lose balance, to keep the eye on the right object, etc. On the other hand, the cochlea also has fluid that vibrates under the action of acoustic waves (which come here from eardrum and auditory ossicles) - these vibrations are felt by the auditory cells.

If the bone barrier between the cochlea and the semicircular canals is too thin, or when a fistula appears in it, then, as experiments have shown, mechanical waves intended for the organ of hearing penetrate into the organ of balance. As a result, it seems to the cells of the semicircular canals that we are moving, and the brain takes appropriate actions in response - and it seems to us that we are turning our head, while in fact we are not turning anything.

In especially severe cases, a person experiences nausea and loses balance. But even with a hole, not all mechanical waves can penetrate the organ of balance from the cochlea, but only those that have arisen in response to a certain sound frequency, therefore, pseudo-intoxication does not occur on any sounds. Semicircular canal dehiscence occurs in about XNUMX in XNUMX people, and although it is now treated with surgery, new data may suggest new, more effective therapies.
