Искусственный снег был впервые получен доктором Рэем Рингером и его коллегами. Открытие произошло случайно во время исследований формирования льда на реактивных двигателях.
Ученые распылили воду в низкотемпературном аэродинамическом трубопроводе перед реактивным двигателем, который затем начал производить снег.

"Like the bombing of the maternity ward in Mariupol," he said, "Even before it hits the news, you see the videos on the Telegram channels." Pavel Durov, Telegram's CEO, is known as "the Russian Mark Zuckerberg," for co-founding VKontakte, which is Russian for "in touch," a Facebook imitator that became the country's most popular social networking site. Artem Kliuchnikov and his family fled Ukraine just days before the Russian invasion. But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. But because group chats and the channel features are not end-to-end encrypted, Galperin said user privacy is potentially under threat.
