One Night Lovely Wife $5.50: Overwhelming Black Belly Husband

Lan Zhirou's heart jumped wildly, great! Several times, if you can't kill the straw bales, then it's not bad to let the straw bales turn their skin on the skin first.

But she never expected that as soon as she raised her head, Nalan Xin'er, who was on the opposite side, was unharmed, and was gracefully continuing to operate the test tube and beaker!

But beside him, there was a scream from Zhao Zhijian, holding his legs and bending down.

The flask of Zhao Zhijian exploded!

What he operates is concentrated ammonia water!

Huang Fushan, who was standing next to Zhao Zhi Fitness, was taken aback. She took a step away and approached Lan Zhirou: "Zhirou, what happened to him?"

Lan Zhirou could not speak.

She was also dumbfounded.

It is impossible to keep authentic in my heart! This is impossible!

She did make hands and feet in the concentrated ammonia water. Before class, she quietly replaced part of the concentrated ammonia water with concentrated nitric acid; and smeared glycerin on the inside of some of the flasks.

Therefore, when she was picking the equipment just now, she rushed forward so excitedly.

The purpose is to pick out the bottles of real concentrated ammonia and clean flasks first, while leaving behind the fake concentrated nitric acid solution and the glycerin-coated flasks.

You know, the heating of concentrated ammonia water only produces ammonia, but if nitric acid meets glycerin...

It was a small explosion!

Although the amount is small and the scale is not large, it is enough to make the person doing the experiment blow up.

Disfigured instantly!

But why, before Nalan Xin'er had an accident, Zhao Zhijian had an accident? !

Zhao Zhijian was taller than them, and the mouth of the beaker was just below them, so he didn't explode his face, but his legs...

Lan Zhirou recalled that when she took the equipment and chemicals, she had read it carefully, and she had also made a secret signal. She definitely did not get it wrong? !

Could it be that the straw bag girl changed her?

But, let's not say that the straw girl is late, she usually learns so poorly, I am afraid that even ammonia and nitric acid can not be distinguished, how can she see through her excellent strategy, and how can she have the opportunity to exchange materials? !

When she was puzzled, she was shocked--

Because the bottle of concentrated ammonia in her hand was pouring into the flask, and the liquid poured out, and the strong smell made her realize that what she was holding was not concentrated ammonia at all, but concentrated nitric acid!

No, the materials in your hands are also dangerous goods!

If the bottom flask is also coated with glycerin...

Then it must explode!

Lan Zhirou was flustered among the sparks.

She grabbed Huangfushan's hand next to her, and said: "Yes, it's terrible, how could this be?"

On the one hand, without a trace, Huangfushan was drawn closer to the table. She, the experimenter, was hiding behind Huangfushan!

Sure enough, a second later, there was a loud bang again, and the flask in front of them also exploded!

Huangfushan's face was hit by the shards of the flask, which was terrible!

Lan Zhirou hid behind her and escaped, but he was stabbed several times on his arm and bleeding continued.

The students and experts in the audience were stunned.

It's just an experiment show, how can it explode?

These are obviously very safe experimental materials, what is going on?

The chemistry teacher was so scared that his legs trembled. In his teaching career for decades, he had never had such a major accident. At this moment, he couldn't earn the honor, and he had to be responsible, and he broke into cold sweat.

It was President Huangfu and Xing Fu who were the most calm. Huangfu Shaoyu was the first to stand up: "Everyone, pay attention to safety, and stop the experimental equipment in your hands! Don't PK, safety is important!"

Xing Fu had already rushed out, and within a minute, he called the school doctor!
