Entertaining experiences at home / Physics experiments for children

If you put water in a wide-mouthed bottle, say a milk bottle, and turn the bottle upside down, what happens? No experience is needed here: the water will pour out, and very quickly!

Well, is it possible to turn the bottle over so that the water from the open neck does not pour out? Let's try. Just not in the room, let's go out into the yard instead. Our experience needs a lot of space. After all, we will not just turn the bottle over, but put it in the household net with which they go shopping.

Water won't pour out of the bottle

Gradually swing the bottle in the net and - once! The bottle makes a full turn... second... third... tenth... And each time it turns upside down and neck down. But not a single drop of water spills 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.

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. ... >>

BMW Electric Vehicle Wireless Charging 10.07.2014

The German company BMW Group announced the development of wireless chargers for electric and hybrid vehicles. In terms of the speed of charging car batteries, the new technology will not be inferior to cable counterparts, but will surpass them in terms of ease of use.

The BMW range includes two vehicles with electric powertrains: the BMW i8 hybrid sports car and the pure electric BMW i3. They are charged using the proprietary BMW i Wallbox system, which is installed by the manufacturer in the buyer's garage with subsequent after-sales service. The equipment is connected to a regular household network and is equipped with additional solar panels to save electricity.

BMW has gone further and is going to use a contactless way to power car batteries. The system developed by the company involves the installation of inductive equipment in the garage floor or other surface that a car can drive on. An induction charging station with a power of 3,6 kW excites a secondary coil mounted in the bottom of the electric vehicle. The energy is converted into direct current, which charges the batteries.

BMW claims the prototype system is 90% efficient and can wirelessly charge the BMW i8 batteries to full capacity in less than two hours. The developers plan to increase the power of the charging station to 7 kW, which will significantly speed up the process of charging plug-in hybrids and electric vehicles.

All conductive components of the system are hidden, so it can be installed outdoors. The generation of an electromagnetic field is not dangerous for humans, since it occurs only when a car appears above the charging platform. If a foreign object gets between the primary and secondary coils, the system will automatically shut down.

It will be possible to control the charging station using a smartphone via a Wi-Fi connection: on the screen of a mobile device, the car owner will see not only the charging status and the remaining time, but also the optimal position for parking above the charging plates.
