Focus Description:

Show the audience two strips of paper (the margins of an ordinary newspaper will do). Put them together and cut off a small tail. Then release one of the strips, and lift the remaining one in your hand high up. Two strips turned out to be one: the scissors glued the paper together!

Focus secret:

Previously, the paper is lubricated with universal glue (such as "Moment"). Of course, not all, but only the ends of the strips. After drying, the glue is lightly sprinkled with flour both in order to mask traces of glue and so that the halves do not stick together ahead of time.

Focus Self Adhesive Scissors

When you fold the strips with the glue sides together, and the scissors at the cut of the paper firmly press the areas of glue exposed from the flour, the strips stick together so that they look like a whole strip.

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 ... >>

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. ... >>

Sleepless night adds fat 31.08.2018

Researchers from the University of Uppsala and the Karolinska Institute argue that even one sleepless night is enough for our body to have, let's say, the conditions for the appearance of excess weight. The experiment involved fifteen young people, averaging 22 years of age, without any sleep problems. They came to the laboratory for two nights, and either slept as usual, or spent the night (8,5 hours) without sleep - the light was on in their room, and they themselves, although they were in beds, did not fall asleep.

The participants of the experiment were divided into two groups: the first group slept both nights, and the second group slept only one night, and the second did not sleep; two weeks later, everyone came back to the laboratory and everything was repeated, only now the groups changed places - all this was done in order to exclude the possible influence of individual characteristics on the results of the experiment.

Before and after each night, blood samples were taken from everyone, as well as fat and muscle tissue. It turned out that those who did not sleep at night, in fat and muscles, the activity of genes and proteins related to cell division and metabolism changed. In particular, those who did not sleep activated metabolic reactions that help store fat; at the same time, they had fewer proteins that are responsible for muscle growth and repair. In addition, the genes associated with inflammation, obesity, and type XNUMX diabetes began to work differently (in particular, the muscles began to absorb glucose worse, and we know that when cells become insensitive to glucose, this is the first harbinger of diabetes).

Scientists believe that the described molecular changes begin with hormones - lack of sleep is known to affect the level of stress cortisol, testosterone and growth hormone, but hormones are already making muscles weaker and preparing to strengthen adipose tissue. It is important that only one sleepless night was enough for all this.
