Take a cork stopper and with a sharp knife cut out one-fourth of it. If you don't have a cork stopper, both a rubber stopper and a piece of Styrofoam (not necessarily round) will do. You can also take a slice of carrot, but a "carrot" sprayer is only good for one time. Then the carrot will dry up.

Pick up two tubes 3-4 mm thick. They can be glass, metal, plastic - whatever you get. Tubes from large goose feathers are also suitable.

Burn two holes in the cork with a nail, as shown in the figure. The tubes should go into them very tightly (for this reason, straws are not suitable: they will crumble when you insert them). Well, before inserting the tubes, steam the cork in boiling water. The vertical tube should protrude slightly above the cork cut.

Ready? Now lower the lower tube into a glass of water, and blow into the upper one. Wow, how our device began to spit! No worse than his venerable relatives: a rubber bulb in a barbershop and a spray gun.

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. ... >>

Learning ability can be seen in the eyes 08.03.2019

How can you know if the interlocutor understood you? You need to follow his behavior, look at how he reacts to certain stimuli. It is this observation that is the main tool of scientists who study a person's ability to learn and perceive new information. But the authors of a recent study in Italy took a different approach. Studying a person's ability to learn, they did not prioritize his external reactions.

The researchers focused on people's visual-motor behavior - in other words, the movement of their eyes - in anticipation of receiving new information. Thus, they learned to read in the eyes - whether their interlocutor understood or not.

Scientists proceeded from the fact that the influence of previously accumulated knowledge on a person's response to external stimuli is formed under the influence of many factors. These include, for example, sensitivity and the way of deciphering sensory information, the way of making complex decisions. After studying all these factors in interaction with each other, scientists from the Center for Neuroscience Research at the University of Taranto tried to establish behavioral responses that indicate a person’s understanding of what will happen in the following minutes.

The leader of the study, Professor Uri Hasson, shared details of how it went. A group of subjects were seated in front of computers and asked to look at the center of a monitor while figures appeared and disappeared in other parts of the screen. "This happened with a certain frequency, - said Professor Hasson. - And we watched what happens with the eyes of the subjects before the appearance of a particular figure." With the help of sensitive equipment, scientists were able to record the smallest involuntary eye movements that occurred in the rhythm of changing the picture on the screen. Each time before the appearance of a new figure, the eyeball of the subjects moved less than 5 mm. This minimal movement became clearer as the person learned the rhythm of the changing figures on the monitor. It indicates that the brain is preparing in advance for the upcoming event.

Analysis of the obtained data allows obtaining information about a person's ability to learn. The researchers also claim that the method they have applied makes it possible to separately consider the state of mind of a person at the moment preceding the "usual" reaction to the appearance of an external stimulus - verbal or, for example, pressing a button. According to Professor Hason, we are talking only about the first results that need further study. But, according to him, in the future, scientists will be able to determine a person's ability to perceive new information by looking at his eyes. The involuntary eye movements recorded by the researchers are the result of subconscious processes, which makes it possible to reliably judge the forthcoming reaction of the subjects to external stimuli.
