Focus Description:

The display will require three glasses, red cabbage, baking soda, white vinegar, a bowl of hot water, and a sieve.

In the first glass, put a teaspoon of soda and top up with water. When the baking soda dissolves, the liquid will become clear. Cut up some red cabbage. Soak it in hot water. The liquid will turn purple. Pour it through a sieve into a second glass. Fill a third glass with vinegar. It looks colorless. After finishing the secret preparations, proceed to the demonstration. Don't show the glasses at first. Just start talking:

- Once the Roman emperor Julius Caesar invited his friends Brutus and Antony to a cup of tea. "Let's drink something," suggested Caesar. "Here's some water for you, Brutus." Take out the first glass and put it on the left. "Here's some water for you, Anthony." Take out the third glass and put it on the right. "Here's some blackcurrant juice for me." Take out the second glass with purple liquid and put it in the middle.

Brutus said, "Oh! Why do you have juice, and we must drink plain water?" And Caesar answered: "You will receive it." Pour some purple liquid into a glass - the water will turn blue. Antony said, "I don't want water either! I'd like strawberry juice." Caesar replied: "You will have it." Pour some purple liquid into the third glass - the water will turn red.

"Perhaps I'd like more strawberry juice, too," Brutus said. Caesar replied: "Easily!" Pour some red liquid from the third glass into the first - the glass will also have red "juice". "It seems to me," Caesar said, "that I, too, would prefer strawberry juice." Pour some of the red liquid from the third glass into the second - now all the glasses are filled with red.

Focus secret:

Red cabbage juice turns red when reacting with acid and blue when reacting with alkali.

When you pour the strong acid from the third glass into the weak alkali of the first glass, the acid clogs the alkali and the solution becomes more acidic and red. The same happens with the strong acid and the indicator in the third glass.

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 ... >>
