Пенополистирол или просто пенопласт представляет собой газонаполненный материал, получаемый из полистирола и его производных, а также из сополимеров стирола.
Так как пенополистирол мало устойчив к растворителям, то он легко растворяется в исходном стироле, ароматических углеводородах, хлорированных углеводородах, сложных эфирах, сероуглероде и ацетоне. С последним из них и встретились эти милые стаканчики.

This ability to mix the public and the private, as well as the ability to use bots to engage with users has proved to be problematic. In early 2021, a database selling phone numbers pulled from Facebook was selling numbers for $20 per lookup. Similarly, security researchers found a network of deepfake bots on the platform that were generating images of people submitted by users to create non-consensual imagery, some of which involved children. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. Apparently upbeat developments in Russia's discussions with Ukraine helped at least temporarily send investors back into risk assets. Russian President Vladimir Putin said during a meeting with his Belarusian counterpart Alexander Lukashenko that there were "certain positive developments" occurring in the talks with Ukraine, according to a transcript of their meeting. Putin added that discussions were happening "almost on a daily basis."
