Entertaining experiences at home / Physics experiments for children

We have done several experiments in which light was decomposed into its component parts. But it is possible, by adding different colors of the spectrum, to get white. True, due to some imperfection of the paints (they contain small impurities of foreign substances, such as glue), we will not get a pure white color, but we can get a very close to white - a grayish color.

For our experiments, we will use a top. It is easy to make: it is, for example, a cardboard circle pierced with a pointed match.

A circle of thick paper will be superimposed on top of the cardboard circle, painted in sectors with all the colors of the rainbow: purple, blue, blue, green, yellow, orange, red. Sectors on a paper circle (they should be the same size) paint over with a very weak, almost transparent layer of watercolor paint. When rotating the top, you get a light gray, almost white color.

Stacking colors

The top can mix different colors. For example, yellow and blue. Paint over the sectors of the circle with these colors one by one. When the top is rotated, it will turn green.

The main condition for the success of the experiments: make the sectors on the circles the same size and do not draw them with a black pencil so that there is no excess contamination of the resulting color.

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. ... >>

Control brightness without a slider 10.02.2010

With energy-saving lamps that are now common, conventional dimmers (dimmers) cannot be used. One of the German companies began producing light bulbs, the brightness of which can be controlled using any simple switch.

The lamp has four levels of brightness: 100, 66, 33 and 5%. Accordingly, the energy consumption changes. To move from one stage to another, you need to turn off the lamp and turn it on again after three seconds. Power switching is carried out by a microcircuit hidden in the base.
