New Scientist's Last Word column recently asked readers to solve a simple-sounding problem: what is the fastest way to empty a full jug of water? The question was posed as part of the series, which invites readers to provide scientific answers to everyday queries.
According to the article, readers responded with scientific explanations, as is the custom for the column. The format turns a practical question about pouring water into an opportunity for collective reasoning, with readers drawing on their own knowledge to propose answers.
The excerpt does not reveal which answer was judged best, or whether readers agreed on a single method. What is clear is that the question was treated as a legitimate scientific puzzle, not just a household tip.
