Focus Description:

The candle goes out without water.

Focus secret:

Light a short candle and put it in a glass. Pour a heaping teaspoon of baking soda into a measuring cup and add half a cup of vinegar. (Cover the cup with a piece of cardboard or a playing card to keep the bubbles from flying away.)

Explain to the audience that the flame is very fearful. To extinguish it, it is not at all necessary to fill the fire with liquid, it is enough just to frighten the fire.

Focus Stealth Fire Extinguisher

Move the cardboard and tilt the glass slightly, as if you are going to pour the liquid onto the candle. Tilt until the liquid touches the rim of the glass. The candle will go out!

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. ... >>

Habits change the brain 03.02.2016

A habit is a deeply rooted type of behavior that works independently of our consciousness. We automatically find the way to the kitchen in the morning, automatically find, for example, a kettle, automatically enter the transport (or get into the car), and do not really think about what we are doing.

It is believed that habitual actions help unload the brain from routine, allowing it to do something more important. That is, from the point of view of neurophysiology, the resources of the prefrontal cortex, our main analytical center responsible for, let's say, conscious life, are unloaded. The habit itself goes into subcortical structures called the basal ganglia, or basal ganglia. (Let's clarify that now we are talking about harmless behavioral rituals, and not about addictions to alcohol, nicotine, etc.) ganglia, and the formation of a habit is accompanied by changes in electrical rhythms: gamma waves that occur during the development of new information are replaced by beta waves when the material is consolidated.

But what happens in the brain, in its basal ganglia, after the habit has already been formed? Neuroscientists from Duke University tried to answer this question: laboratory mice were taught that if they press the lever of a device, they will get something sweet; as a result, some animals continued to press the lever even after the treat was removed from the device. Further, the work of the brain of mice with the habit of pressing the lever was compared with the work of the brain of mice, which understood that there was nothing to wait for and ceased to be interested in the lever.

The basal ganglia control motor activity and literally control our desires, addictions, etc., that is, if we smelled a cake from somewhere that we are crazy about, then it is the basal ganglia that will command us to go where it smells and try do whatever it takes to get food. However, the ganglia generate not only stimulating impulses, but also suppressing, prohibiting ones; that is, the fulfillment of desire ultimately depends on the balance between opposing signals in the basal ganglia. For example, if it’s too dangerous ahead, then, no matter how delicious it smells, you shouldn’t go there, and the neural stop signal is just right here.

So, in mice with a habit of pressing the lever, both signals of the basal ganglia, both inciting and forbidding, increased, however, compared with normal mice, in these mice, the inducing signal became the first by default. That is, if in ordinary animals the basal ganglia “understood” that there was nothing to wait for in this situation and brought to the fore the suppressive impulse that forced them to ignore the lever on the distribution of treats, then in mice with the habit, the stimulating signal in the subcortical structures continued to stimulate attempts to receive treats. .

Changes in brain function persisted for quite a long time, and it was possible simply by the behavior of neurons to predict what this or that mouse would do. The researchers also specifically note that such a rearrangement of signals in places did not occur in any particular group of neurons, but throughout all the basal ganglia (this probably explains why craving for one thing is the reason for a whole bunch of not always healthy habits).
