Scientists have discovered an ancient underground water source. Although it has gone through hundreds of millions of years, scientists are surprised to find that it still meets the standard of drinking water through the detection of scientific instruments. Compared with many bottled water, this underground water source is very precious. In fact, scientists have long discovered that the bacterial content in many open-air water sources is not as high as that in bottled water. This is because nature has a strange law. Once it reaches a certain period, the water source will be automatically updated, and the speed of flowing water source is much faster than that of fixed water source.
While feeling the magical power of nature, researchers also thought deeply about the shelf life of bottled water. On the one hand, the packaging of bottled water is mainly plastic bottles, and its purity cannot be guaranteed by industrial production. If you encounter high temperature, plastic molecules will melt into pure water, which has great side effects on the human body.
On the other hand, bottled water has a small capacity, which is far less than natural water, so even if it has self-purification ability, it can't complete the task in a short time. Therefore, experts have repeatedly reminded people that it is best not to drink expired bottled water, otherwise it will have a bad influence on the human body.
