Getting rich starts at the age of three and a half

Chapter 173 Demonstrate to Song Yuze

Speaking of filtering, Song Yuze actually noticed that there was an extra water tank by half a meter beside the well of Gou Qi's house when he entered the yard.

At this time, a nanny of Gou Qi's family was washing vegetables under the water tank.

In fact, he didn't even need to think about it, he already guessed that the extra water tank should be what Gou Qi said to filter.

But the appearance looks no different from ordinary water tanks, how can the water be filtered clean.

Gou Qi naturally knew the purpose of Song Yuze's visit, and seeing Song Yuze's gaze on the water tank, he knew that Song Yuze must have guessed that the water tank was their filter tank.

But the matter of the filter tank will be discussed later, it is better to talk to Song Yuze about the principle of the filter now.

After speaking, he asked Polygonatum to take out the bamboo filter that had been prepared in advance.

Song Yuze frowned slightly as he looked at the bamboo tube.

Of course, this is still very secretive, after all he still has to listen to Gou Qi talk about the filter.

"This is the filter, and now everyone in my family takes one with them whenever they go out.

It can filter sewage into clean water, which can be much safer.

It is even safer after boiling. "

Gou Qi asked Yuzhu to prepare a large bowl of water, and put a lot of soil in it, making the water look dirty.

"The water polluted by mud is actually very similar to river water, except that the mud in the river has sunk to the bottom and it looks very clear.

But in essence, it is similar to this water, right?

Moreover, there are living things such as fish and shrimp in the river, which makes the water more abundant, and it may be dirtier than the water in my bowl.

Like those things that caused the cause this time. "

Gou Qi made an analogy, and then showed Song Yuze the bowl of sewage.

Looking at the bowl of water, Song Yuze felt that what Gou Qi said made sense without even thinking about it.

"Next, I'll pour this bowl of water into this filter." Gou Qi said while pouring water into the filter carefully.

Of course, there is also a bowl under the filter ready there.

It's just that the water coming out at this time is still a little turbid, which is not the effect Gou Qi wants.

"It was like this the first time, but don't worry. If it's not clear, just filter it again." Gou Qi didn't expect that the muddy water would make such a joke for her. The water that has been filtered once is poured into the filter again.

Song Yuze didn't say a word. He knew that the filter was useful after seeing that the water had changed a lot after passing through it once.

But in his cognition, he still felt that the water was unlikely to become clear.

Just when he was thinking about how to improve the filter, the water had been filtered twice, and the water that flowed out was already clear to the bottom.

"This..." Song Yuze looked at the bowl of water. If he hadn't seen it with his own eyes, he would never have believed that such a bowl of muddy soup would become so clear in such a short period of time.

"If the water is not so dirty, one time is enough. Of course, there are still too few things in mine. If there is enough, one time can be filtered.

Of course, when you use it for the first time, some dirty water will come out first, so this is normal. "

Speaking of Gou Qi, in order to verify her statement, she prepared another bowl of water filled with sand, and then poured it into the filter.

This time, as Gou Qi said, the water came out very clear, which made Gou Qi regain some face.
