Focus Description:

The hat is placed upside down on the glass. Next, you take some coins and hold them over your hat. Everyone sees that the glass is empty.

When you throw coins into a hat, one of them falls into the glass right through the bottom of the hat! Hat, glass and coins can check everything.

Focus secret:

To do this, you must first place a coin on the edge of the glass. Then put your hat on the glass. Slightly slide the coin inside the glass so that only the weight of the hat is holding it.

As you toss the coins into the hat with your right hand, lift the brim of the hat slightly with your left hand. This will release the coin and it will fall into the glass.

The same effect can be achieved with two plastic glasses and a playing card. The coin held by the card slides into the glass.

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 soft material 06.03.2021

Engineers at China's Southeast University have printed liquid metal circuits on a single piece of soft polymer, creating a smart material that twists under pressure or mechanical stress.

Ideally, soft robots could mimic the intelligent and autonomous behaviors of nature — such as the sudden collapse of a Venus flytrap plant — by combining sensation and controlled movement. But technically, this can be difficult to accomplish: it is necessary to build sensors and moving parts into the robot, use an external computer. A one-piece design is required that responds to environmental stimuli such as mechanical pressure or stretch.

Liquid metals could be a solution, and some scientists have already explored their use in soft robots. These materials can be used to create thin, flexible circuits in soft materials, and these circuits can quickly release heat when an electric current is generated—either from an electric current source or from pressure applied to the circuit. As the soft circuits stretch, the current drops, cooling the material.

To make the soft robot capable of autonomous, intelligent movement, a team of Chinese scientists wanted to combine liquid metal circuits with liquid crystal elastomers (LCEs), polymers that can undergo large changes in shape when heated or cooled.

The researchers applied an alloy of gallium and indium with nickel to the LCE and used a magnetic field to move the liquid metal along the lines to form a continuous circuit. Silicone sealant that changes color from pink to deep red when heated provides protection and durability to the chain. Under the influence of the current, the soft material curled as the temperature increased, and the film became redder over time.

The team used the material to develop self-contained grippers that responded to pressure or stretch applied to contours. These fixtures can grip small round objects and then lower them when the pressure is released or the material is stretched. Finally, the researchers shaped the film into a spiral shape. When pressure was applied to the circuit at the bottom of the helix, it unrolled as the temperature of the helix increased.

The researchers say these pressure- and stretch-sensitive materials could be used in soft robots that perform complex tasks.
