Chapter 635: Tricky exam questions

Fortunately, he caught the exam in time.
She glared at Yun Wei. In this exam, she must play well, and she would never let Yun Wei take the lead, so that she could avenge her revenge.
Tomorrow night, he gave Yun Wei a cold look and said, "Okay, start the exam."
Yun Wei glanced, and there were ten students including herself, three boys and seven girls. Sure enough, women still have more love for jewelry?
As for what Fang Lisha is here for, she doesn't know too well. Anyway, Fang Lisha is here for the exam, right?
Ming Ye Leng stood in front of everyone.
He was awe-inspiring, and there was a cold air on his body, revealing apathy.
He waved, and immediately someone brought two dishes.
These two plates are covered with brocade cloth, and I don't know what is covered underneath.
Everyone didn't know what was going to be tested in this exam, so they couldn't help looking at those two things.
Ming Ye said coldly: "Today's exam content is very simple. There is a plate of glass fragments and a plate of broken diamonds. I will mix them together. All you have to do is to distinguish between glass and broken diamonds. Come on."
When everyone heard this, their faces suddenly twitched.
This exam is too simple, right? Those who come here to study, have not all been exposed to jewelry, and who have not come to school with testing equipment?
The molecular structure of glass and diamond is completely different, and it is very convenient to use detection equipment.
If you want to distinguish broken glass and broken diamonds, there is no difficulty at all. You only need to take out the instrument, put the broken glass and broken diamonds in, check it, and you can tell immediately.
Even Lisha Fang, who doesn't understand jewelry at all, understands this truth.
It seems that I have seen everyone’s thoughts, and the corners of the cold lips will cause a rising arc tomorrow: "You can’t use instruments, and you can’t take broken diamonds and broken glass. It can only be distinguished here with the existing things here. ."
He shrugged and said, "I don't know what's in this conference room, although I can find anything you need, as long as it's in this room."
Suddenly, everyone burst into tears and couldn't use any tools, so how to distinguish?
Isn't this clear to embarrass people?
If there are tools, it is not difficult for everyone present here. The detector is the most convenient and quick tool.
Yun Wei also secretly thought: "If you can't use the detector, the people here must have a way to distinguish broken glass and broken diamonds. It's very simple, just use the method of heavy liquid separation. The so-called heavy liquid separation method. , Is a method of separating minerals in heavy liquid with a certain density according to the density of minerals. Pour the heavy liquid into the separatory funnel, put the sand sample, repeated stirring, the denser minerals sink, and the smaller It floats up. The density of glass is about 2.5 and the density of diamond is about 3.5, which is easy to distinguish."
But Ming Ye Leng said that he can't go out, and can't use everything except here, and the heavy liquid is obviously an industrial chemical substance, and there must be no more here.
Obviously, no one can solve this problem with instruments and heavy liquid separation.
Suddenly, all ten people were a little dumb.
Ming Ye Leng looked at Yun Wei impatiently, and in order to embarrass Yun Wei and drove her out directly, he did not think of a way.
