Focus Description:

The balloon is inflated according to the magician's magic.

Focus secret:

This trick is based on the chemical reaction of vinegar and baking soda to form carbon dioxide. You will need a balloon, any dark glass bottle (so that the audience does not see what is happening inside), soda and vinegar.

Focus bottle and balloon

Put two teaspoons of baking soda in a ball and pour a cup of vinegar into a bottle. Announce publicly that you have the power to bring things to life and that you can transmit life energy with your hands. Pass over the bottle. Speak quietly, showing how you transfer energy:

Now the bottle is alive. This bottle is so lively that she wanted to have a party. (Meanwhile, sip the bottle by the neck.) And in preparation for her, she will inflate a balloon.

Build up the anticipation of the audience: leave the bottle for 10 seconds. Of course, nothing happens. Then say:

- Please forgive the bottle. After all, she had only recently begun to breathe and had never blown up balloons in her life.

As if encouraging the bottle, lift the ball and shake it slightly. Soda will sprinkle into vinegar, a reaction will begin with the release of carbon dioxide, which will fill the ball.

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 ... >>

Chinese language sets children to music 28.01.2017

In many modern languages, the meaning of a word depends on the pitch at which it is pronounced; pitch variations of syllables and words can completely change the meaning of what we are talking about. Such languages are called tone languages, and one of the most famous examples is the Mandarin Chinese language, including its variety Putonghua, which is the official language in China, Taiwan and Singapore and which is distinguished four tones. There are also more complex cases, such as Lamnso, the language of the Nso people from Northern Cameroon. Nso communicate with each other already on eight tones, and the meaning of each tone is determined by its variations during the pronunciation of a particular word. It can be assumed that just such languages should be especially closely related to musicality.

This hypothesis was put forward some time ago by psychologists from the University of California at San Diego, who worked with music students. The researchers were trying to understand whether the pitch perception of students whose first language was Chinese is different from the pitch perception of those who speak English from birth. However, at first it was about absolute pitch, that is, the ability to recognize a sound (note) by itself, without interconnection with other sounds.

The scientists did not investigate absolute pitch, but "relative pitch", that is, the ability to determine the pitch of a sound in the context of its neighbors. It is precisely thanks to "relative" hearing that we can, for example, pull up a song after other singers, equaling other people's voices. And the participants of the study this time were not students, but children aged 3-5, some with native Chinese, some with native English. Both were asked to pass several musical tests to recognize the pitch of sounds and their timbre.

As a result, it turned out that both hear the timbre in the same way, but the pitch is different: children with native Chinese felt the pitch better than children with native English. Obviously, both speech skills and musical abilities do not develop in our brain separately, not independently of each other, but, let's say, in close cooperation - "language" affects "music".

However, it does not at all follow from this that a child who studies music must by all means begin to learn some tone language. Music is not only the difference between "la" and the note "si", it is also timbres, rhythms and a mass of syntactic rules by which any piece of music lives. So in order to know and understand music better, you need to deal with it; although it is worth noting that an additional foreign language has never bothered anyone.
