Focus Description:

You have a candle in your hands. Light it up. Now turn the burning candle upside down. The candle is lit from the other side!

Focus secret:

The candle consists of a hollow thin plastic (or paper) opaque tube, painted white. Its length is 15-18 cm, diameter is 2 cm. A metal cylinder 1 cm high moves freely inside the tube. This cylinder has two through holes located opposite each other, into which a needle is inserted. On the needle, in turn, put on a small, made of tin, conical shape, cup, which rotates quite easily around its own axis. The glass is filled with stearin, into which a wick is inserted (Fig. a).

Focus Lighting a candle from the opposite side

To prevent the cylinder moving from end to end with a cup rotating inside it from popping out, the ends of the tube are bent inward by 1 mm. Holding the cylinder through the tube at the top, light the "candle". Slightly loosen the pressure, and the cylinder will fall down. The wick will continue to burn inside. Immediately squeezing the cylinder through the tube, turn the "candle" over. Together with it, a conical cup with a burning wick will also turn over inside. From the side, you will get the complete impression that the "candle" has lit itself from the other side.

It is not necessary to hold a long-burning wick at the bottom, since the gases accumulated in the lower part of the tube will not allow the fire to burn (Fig. b).

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. ... >>

Positive thinking strengthens the immune system 17.11.2021

A group of specialists from the University of Exeter and the University of Oxford (UK) concluded that positive thinking helps to strengthen the immune system.

Scientists conducted an experiment involving more than 135 people. They were divided: some of the volunteers listened to audio lectures on the need to develop positive thinking - to perceive life and the people around them more optimistically, kinder and more condescendingly. Another part of the volunteers listened to the arguments about why the attitude to everything should be as critical as possible.

Volunteers from different groups were measured heart rate and sweating - markers of psychological state. As a result, it turned out that the participants from the "positive thinking" group had their lower parameters, that is, they were more relaxed and less anxious. The level of production of anti-inflammatory components of the immune system in their bodies was also lower, which meant that there was no high risk of infection and disease for a person.

At the same time, the participants in the experiment, who listened to the need for a strict attitude to the world around them, demonstrated increased heart rate and increased sweating. According to doctors, such signs appear when there is a feeling of danger and insecurity, increased stress.

"Positive thinking significantly calms the heartbeat and strengthens the immune system, while negative thoughts have a negative impact not only on the psyche, but also on the physical condition of a person. When we learn not to react painfully to external threats, we strengthen our immunity, thereby increasing chances of recovery," the researchers said.
