Directory / Spectacular tricks and their clues

Focus Description:

For the trick you will need: a small teaspoon of salt, a teaspoon of flour, a plate.

Put a pinch of salt on a plate. Ask the viewer to taste it so that there is no doubt that it is salt. Announce that you can turn it into sugar just by adding flour. Mix flour with salt. Invite the viewer to put a pinch of the mixture on their tongue, and after a few seconds, they will feel the sweetness in their mouth!

Focus secret:

The viewer thinks that you have turned salt into sugar, but in fact the change has occurred with flour. It is saliva that starts the digestive process in the mouth, turning flour into sugar. Salt only speeds up the process, and this transformation becomes noticeable after a few seconds!

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 ... >>

The Greenland ice sheet is melting catastrophically 08.04.2023

Scientists are becoming increasingly concerned about tipping points for climate change. In a new study, they identified two such tipping points for the melting of the 1,7 million square kilometer Greenland ice sheet and the second largest ice storage after Antarctica.

According to scientists' simulations, the release of 1000 gigatonnes of carbon into the atmosphere will lead to the complete melting of the southern part of the ice sheet. With emissions of 2500 gigatons, the entire ice sheet will melt irrevocably.

Since human activity began to noticeably affect the climate, 500 gigatonnes of carbon have been released into the atmosphere. This means that we are already halfway to losing a large number of the Greenland ice sheet.

"The first point of no return is not far from today's climate conditions, so we run the risk of crossing it. Once we start sliding, we will fall off this cliff and will not be able to climb back," said climate scientist Dennis Henning from the Potsdam Institute for Climate Research in Germany.

The scientists conducted complex modeling that took into account all the key climatic processes and factors affecting the melting of ice, including air and water temperature, ocean current activity and precipitation.

Even keeping the 1,5-degree Celsius temperature increase mandated by the Paris climate agreement would not be enough to prevent the Greenland ice sheet from melting, the researchers said.

Scientists also add that at the level of carbon emissions within 1000 gigatons, the sea level will rise by 1,8 meters, if they reach 2500 gigatons - by 6,9 meters.

Unfortunately, there are no signs of reducing emissions yet. Between 2003 and 2016, the Greenland ice sheet lost 255 gigatonnes of ice each year. A recent study showed that the island is losing ice at a much faster rate than previously thought. And this leads to sea level rise and other problems.
