Inflate the balloon and, before tightly bandaging the hole with a thread, insert a strongly bent (almost at a right angle) empty ballpoint pen into it. To prevent air from escaping, plug the outer end of the rod with a match and plasticine.

Pour water into a small bowl (less than the diameter of the inflated balloon). Put the ball on the water so that the bent rod inserted into the ball is on the side, above the edge of the basin. Cut off the plugged end of the rod with scissors. The air will come out of it, and the ball will begin to rotate on the water under the action of the reactive force.

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 ... >>

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 death button in the Qualcomm Snapdragon 810 processor 16.01.2015

Qualcomm announced the developed function of remote blocking of mobile devices in the Snapdragon 810 processor. We are talking about a deeper level of protection for gadgets compared to software solutions in operating systems.

The Snapdragon 810 will be the first chip in Qualcomm's portfolio to feature SafeSwitch, a technology that will enable smartphone and tablet makers to remotely shut down and delete data in their electronics. This feature will come in handy if your device is lost or stolen.

The "Kill Switch" from Qualcomm is implemented at the hardware level, which allows you to protect the phone before the operating system loads, so attempts to reflash the device or install malicious software on it will be useless. Such protection is more effective than the services implemented in Android and iOS.

To return to use a device locked with SafeSwitch, the owner will need to enter a secret PIN code. By the way, this technology is able to determine the location of the lost product.

SafeSwitch will be an option on the Snapdragon 810 and other Qualcomm processors, allowing smartphone and tablet makers to opt-in to this feature or take advantage of other security systems.
