How to put a pointed match? How to make her stand upside down?

There is a very simple way to do this. Cut a circle out of cardboard, pierce it exactly in the center and put it on a match. It turned out a toy well known to you - a spinning top.

Roll it between your fingers and place it on the table. While the top is spinning, it stands.

How to put a match

This experience is so simple that you will hardly do it. After all, everything is clear. It is more interesting to make a wooden top in the shape of a cone, or head over heels, as it is also called. But you can’t cut a good head over heels by hand, you need to turn it on a lathe in a school workshop. To prevent the tip from dulling so quickly, hammer a gramophone needle into it. Its blunt end will serve as an excellent base for head over heels. Only you need to hammer the needle exactly along the axis. Mow - the top will spin very badly.

Kubar is interesting in that it can be adjusted all the time, spurred on with a whip. And while head over heels, he will stand on the edge. Even jumping from the blow of the whip, he will not bend over and, having lowered himself, will rotate all the same straight. And if you push him to the side, he still won’t bend, but bounce.

The conclusion is clear. A spinning top maintains the direction of its axis.

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. ... >>

Windmills are not a hindrance to birds 15.05.2006

Since October 2003, a power plant has been operating in the sea off the southern coast of the island of Lolland (Denmark) with 72 wind-electric generators installed on towers 69 meters high. They produce 595 million kilowatt-hours per year.

Conservationists have raised concerns that the three-blade rotors, each 82 meters in diameter, will kill passing birds or scare them away, forcing them to change their migration routes.

However, conducted twice a year, in autumn and spring, radar observations show that birds, without changing course, bypass the power plant. Only one in a hundred birds is dangerously close to the rotating blades.
