Focus Description:

You are holding a transparent glass with a dark liquid in your hands. For persuasiveness, lower the ruler into the glass and show that it has turned black. After that, cover the glass with a handkerchief. With the words: "My powder discolors any drinks!" slightly lift the edge of the handkerchief and pretend that you are pouring powder into a glass. Now if you remove the handkerchief, there will be pure water in the glass!

Focus Magic Powder

Focus secret:

A black (or any other) color leather insert cut out in its shape is inserted into a glass of water. Therefore, it seems that there is a drink in a glass. The ruler on one side is painted in the same color. Dip it into the glass with the clean side towards the audience, and then discreetly turn the other side and show.

The powder is needed only to confuse the audience and produce the desired effect. If, together with a handkerchief, a thin liner is pulled out of a glass, the drink will turn into water.

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 ... >>

MSI Radeon R9 290X Lightning graphics card 04.03.2014

Micro-Star International (MSI) has officially announced the release of the much-anticipated "lightning" version of AMD's top-of-the-line Radeon R9 290X graphics adapter, the first public demonstration of which took place at CES 2014 in Las Vegas, which was held in Las Vegas.

The MSI Radeon R9 290X Lightning is based on the 28nm Hawaii XT chip with 2816 stream processors based on the Graphics Core Next (GCN) architecture. The video card is built on a non-standard printed circuit board for the PCI Express 3.0 x16 bus in accordance with the MSI Military Class 4 proprietary concept, which involves the use of a high-quality element base that meets all the stringent requirements of the MIL-STD-810G military standard in terms of reliability. The reinforced power subsystem with a digital controller is made according to the formula 12 + 3 phases. Connection to the power supply unit is carried out using one 6-pin and two 8-pin connectors. Besides, in a novelty function Twin BIOS is implemented.

The powerful MSI TriFrozr cooler with the Triple Force structure and an additional plate on the back of the PCB, due to which the accelerator will take up the space of three expansion slots on the motherboard, are engaged in ensuring optimal temperature conditions. The design of this active air cooling system includes a massive two-section aluminum radiator, seven 8 mm copper heat pipes with MSI SuperPipe technology, as well as three fans with pulse-width modulation speed control (one 70 mm with a yellow impeller is located in the center, and two 100 mm with black blades are placed on the sides). You can change the rotation speed of the central and outer "propellers" independently in the BIOS of the video card using the MSI VGA Fan Control proprietary utility.

The Triple Level Signals function allows you to track the degree of load placed on the accelerator by the color of the LED indicator (red - strong, blue - medium, green - weak). Full control over the voltage and temperature of each of the key components of the video card is provided by the 3x3 OC Kit, which combines useful overclocking tools such as Triple Overvoltage, Triple Temp Monitor and V-Check Point.

The model is equipped with 5 MB GDDR4096 memory with a 512-bit interface and a frequency of 5000 MHz. The base frequency of the graphics core is 1080 MHz. The rear panel has two DVI ports, as well as HDMI and DisplayPort outputs. The product is DirectX 11.2, Mantle and OpenGL 4.3 compliant, 4K ready, and supports AMD PowerTune, AMD TrueAudio, AMD Eyefinity and AMD CrossFire technologies.
