Made with platinum cured silicone and inside they are filled with Silexpan, something ala dense memory foam. And as memory foam changes behavior with temperature change this also perform same way.

Main idea is to make cheap good quality things, cheap because Silexpan used for inside part cost much less compared with top quality silicone.

Japanese scientists from the National Institute of Genetics and Niigata University said that the "delta" strain of COVID-19 stopped multiplying due to an excessive number of mutations and the virus began to self-destruct naturally. This is how scientists explain the sharp decline in the incidence of coronavirus infection in the country: at the end of August, the Japanese detected twenty thousand patients daily, and now new cases do not exceed a hundred people a day with a population comparable to ours.

Scientists from the UK found that men are 41% less environmentally friendly than women. A significant role in this was played by the adherence to a meat diet, that is, the actual support of one of the most environmentally unfriendly areas of agriculture - animal husbandry.

Scientists analyzed the emissions from the production of more than 3 thousand products, as well as the diet of 212 Britons. It found that animal products account for 31% of the greenhouse gases that are generated during the production of this food.

Experts stressed that the high demand for meat is exacerbating the climate crisis, as livestock production leaves a large ecological footprint.

They added that, in general, men eat more (!) and are also more committed to a traditional meat diet, which is why their foods are responsible for a larger share of the emissions.

Men's purchases generate 16% more carbon emissions than women's purchases.

Representatives of the sterner sex often use cars, buy gasoline and diesel fuel. In turn, women travel more by public transport, which significantly reduces their share in greenhouse gas emissions.

In addition, men are more likely to spend on food outside the home, alcohol and tobacco, while women’s money is mainly spent on health, clothing and home improvement.

The reluctance to document a project isn't just due to laziness or lack of time. It stems from the designer's unwillingness to bind himself to upholding solutions that he knows are preliminary.

If the organizational structure is likely to pose a threat, nothing will be documented other than what cannot be challenged.
