Focus Description:

You have a "magic wand" in your hands. Shift the stick to one or the other hand, touching it first to one, then to the other hand, clenched into a fist. Candies will appear in your hands one by one.

Focus secret:

The sweets were inside a hollow "magic wand", which, one at a time, fell into one or the other of your hand from the "window" of the wand during the demonstration.

Focus The wand conjures candy

The stick is made of thick paper. A wooden cylinder, each 2 cm long, is glued into a paper tube with a diameter of 5 cm on both sides. On the side of one of them, at the place where the cylinder ends, a rectangular window 6 cm long is made in the tube so that one candy can fall out freely.

The tube is painted like a "magic wand": at the ends - white, and in the middle part - black. The length of the "magic wand" is 40 cm. Candies are pushed through the entire length of such a stick.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

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 ... >>

Dark matter got darker 10.04.2018

An international team of astronomers led by Richard Massey from Durham University in England has refuted the "brightening" of dark matter, that is, the existence of a non-gravitational interaction between clumps of invisible matter.

Scientists reported the discovery of signs of non-gravitational interaction in dark matter, which is located in the galactic cluster Abell 3827, 1,3 billion light-years from Earth. The researchers studied the distribution of mass in four colliding galaxies using the gravitational lens effect, when an object bends the paths of light rays.

It is assumed that there is a halo of dark matter in the centers of galaxies, which explains the peculiarities of the circular motion of stars around the nucleus. Three clumps of dark matter in Abell 3827 corresponded to the location of three galaxies, but the fourth clump in its motion lagged behind the nearby galaxy by five thousand light-years. This, according to scientists, indicated that not only gravitational forces act in dark matter, but also some other interactions.

In the new study, astronomers used the Atacama Large Millimeter Array and Very Large Telescope radio telescope complexes in Chile, which made it possible to conduct more detailed spectroscopy of galaxies and minimize distortion due to the effect of gravitational lensing. It turned out that the location of the halos in galaxies corresponded to the ?CDM model, according to which dark matter interacts only through gravitational forces.

Dark matter, according to cosmologists, makes up 22 percent of the total mass of the universe (74 percent is dark energy, and the rest is visible matter). It does not interact with ordinary matter through electromagnetic and other fields, with the exception of gravity. The conclusion about its existence was made on the basis of observation of astronomical objects that behaved as if they were affected by a mass hidden from direct observation. At the moment, no particles have yet been discovered from which dark matter could exist.
