Focus Description:

The magician fills a plastic margarine jar to the brim with dry rice. Then he covers it with exactly the same jar upside down, turns the jars on their sides, pressing them tightly against each other, and wears them around all four corners of the room, saying that rice is magically transferred to the north, south, west and east. Our rice has traveled the world. It may not have doubled in taste, but it has doubled in size.

We put the jars on a tray, remove the top one, and the rice is scattered all over the tray, it has become twice as large!

Focus secret:

For this trick, we need to pre-conjure over plastic jars. We need two exactly the same. Take the lid from the jar, carefully cut off the edge of it. We glue the lid inside one of the cans approximately in the middle. Now its volume has halved. Let the kid decorate both jars so that they look exactly the same. To do this, they can be pasted over with colored paper and shiny stars.

Now it only remains to remember an important detail at the end of the trick: after traveling around the world, a jar with a glued lid should be at the bottom.

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. ... >>

Plasma gun - a new NATO weapon 30.07.2012

Scientists from the Picatinny Arsenal continue to work on an unusual type of weapon using a laser-induced plasma channel (LIPC). The bottom line is to use a laser beam, which "tears" electrons from air molecules and creates a plasma conductive cord that destroys equipment and manpower.

LIPC lead scientist George Fisher shared the barest details of this secret project: "We can create a very short laser pulse with tremendous energy. In 2-3 trillionths of a second, you can fit energy that exceeds the needs of an entire city."

This nanosecond electrical pulse (nsEP) can be a very powerful weapon. The Pentagon wants to use it to send up to 50 billion watts of optical / electrical power to the target. This is much more than any existing combat laser with a power of about 100-1000 kW. The most powerful nsEP will be able to instantly kill any living creature. Its effect on armored vehicles and fortifications has yet to be studied - it all depends on the power and duration of the pulse.

At present, military scientists have faced a number of serious technological barriers to the creation of LIPC. The plasma channel, which must be learned to keep stable at least for a short time and direct it at the same time to the target, self-destructs. In addition, there is a danger that during the formation of the channel and focusing the beam on the air, the energy will destroy the optical system of the laser and hit the shooters themselves.

It is necessary to reduce the load on the optical systems and keep it at a low level until a plasma channel is formed and energy flows to the target. There are also other problems, in particular the synchronization of the laser with high voltage, the creation of capacious power sources and a reliable field device, that is, the weapon itself. It is possible that a number of these problems will be solved using the most powerful NIF pulsed laser, which recently set a record for laser pulse power.

Apparently, the future plasma-laser gun will be quite large and will only fit on ships or trucks. However, the advantages that it promises on the battlefield will more than pay off the dimensions and huge power consumption.

It is possible that a number of these problems will be solved using the most powerful NIF pulsed laser, which recently set a record for laser pulse power.
