Focus Description:

Put a decanter on the table, put a playing card or a small cardboard 6x9 cm in size on the neck of the decanter.

Place a coin of any denomination in the center of this card. After that, invite the audience, without touching the coin with their hands, to lower it into the decanter. Attempts of those who wish, as a rule, are not crowned with success. Then you knock it off the decanter with a strong click on the edge of the corner of the cardboard. The cardboard flies to the other side of the room, and the coin falls to the bottom of the decanter.

Put a card on a glass of water, a ring (metal or glued from cardboard) on the card, and put an egg on the ring with a sharp end. Then invite the audience, without touching the egg with their hands, to dip it into a glass of water.

Focus secret:

Wishing, as a rule, is not. Then you flick knock out a card, and the egg and ring fall into the glass.

Focus Coin in decanter

To demonstrate the trick, you will need: a decanter, a glass of water, a coin, a playing card (or a small cardboard box), a metal or cardboard ring, and a boiled egg. It must be remembered that clicking on the edge of the corner of the map must exactly go in the horizontal direction. The water in the glass softens the fall of the egg and prevents it from breaking.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Bacteria help keep skin healthy 10.10.2014

We try to rid the skin of bacteria and acquire the latest cosmetic products that promise ever more powerful and long-lasting antibacterial effect. Indeed, microbes on the skin can cause a lot of trouble, such as acne, or inflammation of the sebaceous glands, which is believed to be due to Propionibacterium acnes bacteria. So it's not in vain that we try to keep our skin clean by washing off dust, dirt and sweat as often as possible.

But not all bacteria are equally harmful. Researchers from AOBiome (USA) spoke at a conference of the American Society for Microbiology about the benefits of nitrifying bacteria for the skin. They are found in abundance in water and soil, being important players in the nitrogen cycle. The products of their vital activity are nitrites (salts of nitrous acid) and nitric oxide NO. But just such compounds play a big role in physiology - in the regulation of inflammation, wound healing, in the expansion and narrowing of blood vessels. (For example, it was recently discovered that nitric oxide suppresses the autoimmune response, and this is just one of its ever-growing functions.) In addition, nitrifying microbes could absorb ammonia, which is released with sweat and disrupts the acid-base balance. balance on the surface of the skin epithelium. Therefore, the authors of the work came up with a simple idea to plant microbes on a person and see if the skin condition changes.

Volunteers who agreed to the experiment were given a suspension of Nitrosomonas eutropha bacteria taken from the soil on their face and head; some received a bacterial-free placebo suspension. For the first two weeks, none of them used shampoos or any other hair care products; on the third week, everyone returned to their usual hygiene and cosmetic procedures.

Bacteria took root in people: in those who were smeared with a bacterial substance, the DNA of nitrifying microbes was found in 83-100% of cases after a week, and in 60% after two weeks. The main result, according to the authors of the work, was that the condition of the skin with bacteria improved, and the stronger, the more bacteria remained on it. Volunteers did not have their own N. eutropha, this was specially checked before the experiment, so that the effect could be attributed entirely to the bacterial suspension. As for the side effects, they could not be found.

N. eutropha can exert its effect not only directly by releasing physiologically active nitrogen compounds and lowering pH, but also by influencing the skin microflora. After all, no matter how hard we try, it is impossible to completely get rid of skin bacteria, and nitrifying microbes could adjust the skin's own microflora so that it behaves well. Despite the small statistics (only 24 people participated in the experiment), the positive result from the presence of N. eutropha was quite obvious. However, it is still necessary to confirm the obtained data in a more impressive experiment, at least in order to once again make sure that there are no negative side effects.
