Entertaining experiences at home / Chemistry experiments for children

A small amount of potassium permanganate crystals is poured onto an iron sheet or brick and moistened with concentrated sulfuric acid. Around this mixture, thin chips are folded in the form of a fire, but so that they do not touch the mixture. Then a small piece of cotton wool is moistened with alcohol and pinched between the fingers, holding the hand over the fire.

A few drops are squeezed out of the cotton: alcohol so that they fall on the mixture. The fire will instantly ignite. In the experiment, alcohol is vigorously oxidized with oxygen. The heat released at the same time ignites the fire.

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. ... >>

Faux leather against drugs 30.09.2018

Researchers from the University of Chicago offer a peculiar way to deal with drug addiction - with the help of patches of genetically modified skin.

As you know, not so long ago, biotechnologists have a very effective tool for making the necessary amendments to the genome - a tool called CRISPR (which we have repeatedly written about). Using CRISPR, it is possible to insert genes that code for certain proteins into the DNA of skin cells, and then, after waiting for the skin cells to form the desired piece of skin, transplant them onto the body.

Previously, Xiaoyang Wu and his colleagues had already done similar experiments, forcing skin cells to synthesize insulin, so that the transplanted patch helped maintain normal blood sugar levels in diabetic mice. Now, instead of insulin, they decided to introduce the gene for butyrylcholinesterase, an enzyme that destroys cocaine, into skin cells. We have this enzyme anyway, it works with different substances, and the cocaine molecule is just similar to the molecules that butyrylcholinesterase deals with. However, the enzyme that we have is not very active, at least in relation to cocaine. But there is an improved laboratory version of it, which breaks down the drug 4400 times more efficiently.

Butyrylcholinesterase is much larger than insulin, and there were doubts that skin cells, which normally do not synthesize it (the enzyme is normally formed in the liver), will be able to handle it. However, the transplanted anti-cocaine skin worked as it should: two weeks after the transplant, the mice calmly tolerated the dose of the drug that had literally killed them before.
