A pierced coin. Focus Secret

Focus Description:

Show the audience a whole large coin. Take an ordinary pencil or other similar object and pierce the coin right through. The pencil will go halfway into the coin on one side and come out on the other. Now, just as slowly, pull the pencil out of the coin. She, as before, will remain intact.

Focus secret:

The secret of the trick lies in a specially prepared coin. A through round hole with a diameter of 6-7 mm was made just above its center - the diameter of a pencil. The half-circular half of the coin is cut out from the reverse side of the coin. It is inserted back into the cut out place.

Focus pierced coin

With the help of a spring embedded inside it, this half can bend outward when pressed through the hole and slam back, freed from pressure. Attached to the inside of this movable half of the coin is a circle made from the face of the coin - exactly the missing part.

When the half of the coin slams shut, this circle must fit exactly into the through hole and close it with itself. If such a coin is viewed from the outside, it will look completely intact.

Holding the bottom of the coin (the whole half of it) with the front side facing the audience, slowly insert the pencil into the hole hidden by the circle. Moving further, the pencil will open the movable back of the half of the coin and come out of it. When the pencil is removed from the coin, a spring will instantly return the half (invisible to the audience) back into place.

The hole will also be closed by a protruding circle, and the audience will see, as at the beginning, a “whole coin,” although they have just seen a pencil pierce through it.

If all the moving and protruding parts of the coin are carefully adjusted, the coin, both initially and later, can be safely shown to spectators from both sides. Even with a thorough inspection, they will not notice anything.

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. ... >>

The brain turns words into pictures 04.04.2015

When learning new words, our brain shifts from reading letters to perceiving the word as a single visual image, researchers from Georgetown University came to such conclusions. Their experiment involved 25 people who were asked to learn a set of specially made up nonsense words. In parallel, with the help of functional magnetic resonance imaging, the work of the brain was monitored. It turned out that as the proposed verbal nonsense was learned, the activity of neurons changed. That is, at first they perceived the new word as something incomprehensible, consisting of separate characters, but then it became familiar, and was included in the dictionary as a single "picture".

For a long time it was believed that text recognition in the neural apparatus occurs by letter. At first glance, this is how it should be, because words consist of letters, and we ourselves learn to read, analyzing what is written letter by letter. However, in 2009, in the journal Neuron, Maximilian Riesenhuber and his colleagues published an article describing the activity of the region of the left visual cortex, which recognizes words immediately and completely. (By the way, the symmetrical area in the visual cortex on the right is responsible for face recognition.) Of course, the question immediately arose of how the "visual dictionary" is formed. This is where the invented words were needed, which the participants in the new experiment had to learn.

As a result, neuroscientists were able to see how visual neurons gradually tune in to a new vision of the text, how the transition from reading by letter to recognizing the word as a whole takes place. Obviously, this speeds up and facilitates reading - as well as recognizing faces as a whole, and not by individual features, helps to quickly recognize another person and facilitates communication.

New data may help those people who have neurological problems with reading. It happens that the brain is simply not able to learn words by the usual spelling method, like a sequence of letters. And then, perhaps, a method in which the emphasis would not be on letters, but on the word as a single visual image, would come in very handy. Perhaps, by stimulating the corresponding zone of the visual cortex, we can achieve great success in learning foreign languages. True, in addition to writing, you also need to know the pronunciation of words, but for this you already need to turn to other parts of the brain - those that are responsible for the perception and analysis of speech sounds.
