Focus Description:

The magician makes the water red and then normal again.

Focus secret:

Prepare an opaque jug (you can also take a glass jar pasted over with colored paper with various "secret" symbols) and five glasses. Pour water into a jug. Place one measure of sodium carbonate in the first beaker, three drops of phenolphthalein solution in another, and four measures of sodium bisulfate in the third.

The remaining two glasses are only needed to make the transformations look more complex. Add a few drops of water to each glass to dissolve the chemicals. Remember in which glass sodium bisulfate is dissolved.

Show the audience that your jug ​​contains ordinary water (you can even drink a little). Fill all the glasses with water from the jug, then pour them back into the jug, except for the sodium bisulfate solution. After a few "alchemical incantations," fill the empty glasses from the jug with a liquid that has turned blood red. Pour the liquid back into the jug, now with the sodium bisulfate solution. A few more spells - and you can pour liquid from a jug into glasses, which again turned into "water".

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 ... >>

Bourns pulse transformers for isolated power supplies 06.03.2020

Bourns has announced a new series of isolation transformers, the HCT series push-pull transformers, to power isolated CAN, RS-485, RS-422, RS-232, SPI, I2C, and low power LAN interfaces.

A feature of the series is the air gap between the primary and secondary windings increased to 8 mm, which allows to provide insulation voltage Vrms=4200 V (for 60 s). HCT series transformers comply with IEC 60950-1, IEC 62368-1, IEC 60664-1 and AEC-Q200.

The HCTs are designed for use with the SN6501, SN6505B, and SN6505D drivers from Texas Instruments, and the MAX256, MAX258, MAX13253, and MAX13256 drivers from Maxim Integrated. In addition to supplying interfaces, HCTs can be used in medical equipment (sensors), industrial automation devices (DC/DC converters), and other applications where isolation from high voltages is required.

Key Features:

Input voltage: 3,3...5 V;
Output voltage: 3,3...15 V (at I=350 mA);
Operating voltage: 800V;
Insulation voltage: 4200V;
Operating temperature: -40°С...125°С.
