You can arrange a theater in which electrified paper dancers will dance. Only the comb for this theater is too weak. Take a piece of window glass 40 cm long and 25 cm wide. Dry this glass thoroughly by the stove or radiator. It must be completely dry. Put the dried glass between the pages of two thick books. Let it lie above the table at a height of about 3 cm.

From thin tissue paper, cut out figures of dancers 1,5-2,0 cm high. Stick a pin in the leg of each dancer so that it does not “fly up” and stick to the glass. Put these figurines on the table under the glass.

In order to electrify the glass, rub it harder with a woolen or better with a silk rag. It must also be completely dry. Soon, the figures, attracted by electricity, will begin to stand up and bounce.

If the experiment does not succeed immediately, dry the glass and rag again. Every even the slightest trace of dampness is the enemy of this experience.

But with organic glass, the experience will turn out great. A sheet of plexiglass is perfectly electrified if you rub it with a wad of paper or even just with a dry palm. It attracts dancers so much that you can make them not from tissue paper, but from plain paper. You can cut out figures of different colors, different types. Clowns and frogs, graceful ballerinas and elephants will dance equally briskly!

By the way, you can use the "electric dance hall" for another fun experience. Make dice out of elderberry pulp or styrofoam and put them under glass instead of dancers. The three glass cubes will jump, turn and show a different score each time!

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. ... >>

Smart watch with a living organism inside 25.12.2022

Scientists at the University of Chicago have come up with an unusual solution to the problem of changing gadgets too often and creating electronic garbage profusely - they have created a smart watch, which is provided by mucous - the easiest organism to feed and care for, almost like a Tamagotchi. The solution even allows you to establish an emotional connection with the smart watch.

The use of a conductive protozoan organism - the plasmoid slime Physarum polycephalum - made it possible to create a smart watch that works only if the body in the body is healthy and supplied with food. In fact, the watch is a kind of simple cyborg with interconnected living and inanimate parts.

It is expected that the presence of a living organism in electronics will prevent people from mindlessly changing gadgets at will. Irresponsible consumption leads to an increase in the volume of electronic waste on the planet - 40 million tons are added annually. The study of how a living device affects people's behavior showed that this changed the attitude of users to the technologies used - in fact, we are talking about a two-way mutually beneficial cooperation between the watch and its owner.

Surveys showed that when using worn gadgets, it was purely consumer one-way use, while the interaction with the experimental model resembled two-way communication, since it was a living organism - many could not just throw away the watch or just put it in the closet indefinitely.

The prototype "live" clock is able to show the time and is equipped with a heart rate sensor. The organism is housed in a special recess in the watch case, and the user must regularly feed it a mixture of water and oatmeal to encourage growth. When the body reaches the other side of the notch, a conductive circuit is activated, allowing the heart rate sensor to work. Also, the body goes into sleep mode if it is not fed - it can be brought back to life after days, months or even years.

The organization of human-computer interaction is mainly focused on improving productivity, but here it was said about the emphasis on daily care and nutrition, so the result of the study is partly a work of art.

Scientists conducted experiments with five participants, during which the latter wore hours for two weeks. The emotional connection turned out to be more significant than when using toys like Tamagotchi - in such cases, after death, it is easy to reboot. Moreover, the participants in the experiment experienced quite a lot of stress when they were ordered to stop feeding the creature in the watch case, experiencing guilt or even grief.
