Focus Cotton Lemonade

Focus secret:

Take a metal glass with a lid and a few pieces of cotton wool. First show the audience that the glass is empty. Then dip a few pieces of cotton wool into it and close the lid. Put ordinary thin-walled glasses on the table. Now you can remove the lid and ... pour lemonade into glasses. Yes, cotton wool in your hands has turned into a real lemonade.

For this trick, any cotton wool will do and you will need a glass with a secret. It consists of three parts: glass A, insert B and lid C. Solder two springs to the inside of the lid - they will hold the insert into which you will pour the lemonade in advance. At the moment when you put the lid on the glass, its walls press on the springs, and the insert falls out of the lid into the glass. The cotton wool remains between the bottom of the glass and the bottom of the insert.

Springs are easiest to cut off from the spring of an old alarm clock. You will understand their profile from the picture. You can choose the sizes of the glass, inserts and lids yourself. Just keep in mind that the diameter of the glass is slightly smaller than the lid. The material for them can serve as tin from large cans.

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 ... >>

Homework and academic performance 13.05.2015

Is the proverb "Repetition is the mother of learning" true? A new study on this topic was conducted by Spanish sociologists from the University of Oviede under the leadership of Javier Suarez-Alvarez.

Scientists studied the performance of almost eight thousand high school students in the province of Asturias. The average age of students is 13,78 years, and 47,2% of them were girls. The researchers were interested in whether homework in subjects such as math and science affects performance.

The survey showed that half of the students do their homework every day, and a third almost every day. At the same time, in half of the cases it takes from one to two hours, in a quarter - from half an hour to an hour, and in a fifth - more than two hours. A third cope with it on their own, half sometimes need help.

These data were compared with the results of control works, which were evaluated in points, on average, about 500 points were obtained. As it turned out, those who do their homework every day and do it without the help of adults get fifty points more than others. An interesting result was obtained when comparing academic performance and the duration of homework: 20-minute work gave an estimate of 450-470 points, and 90-minute work - 510-530. Further sitting over the textbook is not necessary: the grade drops.

From the study, the authors draw the following conclusion: “Our data is a clear signal for teachers: homework remains the most important tool for quality education, even in the current information society. "Homework should not repeat the lesson as it makes the task easier. On the contrary, it should be a little more difficult for the student to improve their skills, but not so difficult as to cause frustration."
