Кристаллизация в реальном времени из пересыщенного раствора сульфата натрия кажется совсем нереальной.

Тут, конечно, важно, что раствор пересыщен. Дело в том, что существует максимальное количество сульфата натрия, которое можно растворить в воде – такой раствор называется насыщенным. И если вы захотите добавить ещё сульфата, то он уже не растворится. Но можно пойти на хитрость, и растворить ещё, хоть и временно. Например, используя горячую воду вы можете растворить ещё немного сульфата, и когда раствор остынет, концентрация соли будет выше, чем в насыщенном растворе, то есть он станет пересыщенным. Но когда мы нарушим это хрупкое равновесие, например, опустив в такой раствор стеклянную палочку, то весь избыток растворённой соли сразу кристаллизуется, как на гифке.

Should You Buy Bitcoin?

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
