Directory / Spectacular tricks and their clues

Focus Description:

The wizard makes several mysterious passes with his hands over a wand or pencil, which ominously begin to move on their own.

Focus secret:

The focus should be on a smooth, hard surface.

Place the stick (pencil) on the table and very slowly draw circles around the stick with your finger. When you remove your finger, the stick will follow. Tell the audience that the finger created a static field that attracts the stick like a magnet.

The trick is that when you move your finger away from you and away from the stick, you blow on it without being noticed. The audience is so busy watching your finger move that they won't notice you blowing on the stick, causing it to roll on a flat surface.

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 ... >>

Smart new generation military uniform 08.05.2012

The US Office of Naval Research has published a competitive proposal for the development of a new generation of military uniforms. The unique "smart" clothing will continuously measure the vital signs of soldiers, determine the location of the military, the severity of injuries, and even transmit the coordinates of wounded soldiers to medical staff and promising evacuation robots. All the devices needed to perform these tasks will be integrated directly into the fabric of the uniform.

This initiative, called Intelligent Clothing for Rapid Response to Aid Wounded Soldiers, is not the first attempt by the US Army to revolutionize military uniforms. So, in 2004, within the framework of the "Soldier of the Future" program, bulletproof vests with woven electrical wiring and gel sensors were developed, which were supposed to transmit information about the state of the soldier to the command and control center. Later, the Soldier of the Future program was canceled and the electronic clothing project remained unrealized. However, apparently, the idea has not died, and the Pentagon will still try to put it into practice.

A promising high-tech uniform will use an array of sensors embedded in the fabric, integrated into a single system. They will control the vital functions of a soldier, as well as determine the nature and location of the injury, assess the depth of penetration of a fragment or bullet, and identify the affected internal organs. In addition, sensors must be able to detect the presence and exposure of the body to hazardous chemical, biological, radioactive, and explosive substances. For this, special sensors and specific biomarkers in blood, saliva, sweat, etc. will be used.

Thanks to the timely detection of various threats, the soldier will have time to take measures to protect his life, and the doctors will be able to prepare in advance to provide assistance and win precious minutes during the so-called "golden hour", when the chance of survival of the wounded is maximum.

Developing a smart fabric is not an insurmountable task. Over the past five years, commercial enterprises have made impressive progress in this area. Fabrics have been created that can detect, for example, the blood sugar level of diabetics or monitor breathing, pulse and blood pressure in athletes. There is even tissue that can prevent injury, more precisely, to ensure that a person does not overload the muscles.
