Entertaining experiences at home / Physics experiments for children

I am not suggesting that you catch a live octopus and try to electrify it with friction. The octopus will be artificial, from the newspaper. Cut a strip 8 cm wide from the edge of the newspaper sheet and cut eight "tentacles" from it. Just do not cut to the end, otherwise it will turn out not an octopus, but noodles!

A real octopus dies without water. And our paper octopus absolutely does not tolerate even the slightest dampness. Dry it well: in the winter by the stove, and in the summer in the sun. Lay out the straightened dry octopus on a dry table and electrify it by running a clothes brush along the course of the tentacles. Of course, the brush must also be completely dry.

Lift the electrified octopus with your left hand, turning the uncut side of the sheet into a ring. The tentacles will hang down... Wait a minute, what's wrong with them? Look, they spread out like a bell, as if preparing to capture prey!

Come on, be bolder! Put your right hand from the bottom inside this bell! Of course, the tentacles of the octopus will immediately grab her, stick around her. It's good that the paper monster has no suction cups!

This fun experience gives you something to think about. Electrified tentacles grabbed your hand? That's right, they were attracted to it: after all, electricity attracts. But that's why they splayed out like a bell from the very beginning? After all, they should have been attracted to each other, stuck together?

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. ... >>

Standardization of laptop power supplies 24.08.2010

Many manufacturers Acer, ASUS, Quanta Computer, Compal Electronics, Wistron, Pegatron Technology and Inventec supported this idea.

IEEE hopes that as a result, consumers will benefit from lower costs, as a single power supply can charge the batteries of several laptops, and when buying a new device, there will be no need to purchase a power supply for it.
