“

Why, because since Li Zhong and the others made a joke on the pepper bottle last time, now they have learned a lot better, and they are all waiting for each other to speak first, but I didn't expect Fang Wenlai to jump into this pit......

Wu Zhi smiled, pinched a matchbox in his hand, and gently pushed it with one finger: "Look, it's like this, this package is actually like a drawer......"

"I see!" Li Zhong suddenly realized, while laughing, he also hurriedly pushed open the matchbox in his hand in a decent manner, only to see that there were wooden sticks like little fingers in the "drawer", and there was a "head" at one end of the wooden stick, which was red.

Li Zhong touched his head, it seemed that he still didn't ask, and was about to open his mouth, Wu Zhi had already opened the conversation box first, avoiding his embarrassment: "You take out a match, just use a little force on the side of the matchbox like this!" ”

Snort –

Sparks had lit up between Wu Zhi's fingers.

Li Zhong and the others hurriedly tried one after another, only to hear the sound of sneering one after another, and the hands of the six people were lit up with beautiful flames.

For the people of the old days, the flame meant hope. And for Li Zhong and others, the matter of making a fire can become so simple, and the spark that is generated is so big and lasts for such a long time, this is simply an unimaginable thing, why, why can such a small wooden stick with a red head be able to do such a magical thing and shine?

Even Fang Wen, a well-informed son, was stunned when he looked at the flames in front of him.

The match is obviously something that is about to be completely eliminated in modern society, but for the people of the Northern Song Dynasty, it is still a great invention that has taken a very big step forward, which is beyond doubt.

They are not shocked, it is impossible to drop things.

Wu Zhi smiled, and quietly touched the lighter again.

With a click, Wu Zhi lit the lighter.

The six matches were extinguished, leaving only the light of the lighter flickering among the six.

"W-what is this?" Li Zhong was so excited that he almost stammered.

"Lighters."

"Lighters? Play for me! Fang Qiong and Jin Lian came to grab it together, Jin Lian didn't win, and was snatched into her hand by Fang Qiong first.

"Hehe, six, sixth sister, why don't I play with you first......" I didn't expect Fang Qiong to grab it, but she suddenly became reserved, and returned the lighter to Jin Lian.

"Good apprentice, I still know how to honor my master first!" Wu Zhi praised her.

"you!" Fang Qiong didn't stutter at all in front of Wu Zhi.

It seemed that it was Jin Lian's previous lion's roar that completely shocked Fang Qiong.

Jin Lian took the lighter, but she couldn't play. The lighter is colored transparent, the cheapest and most common one, and when the golden lotus shakes it, you can see the oil swaying inside.

"What's here? Is it water? Jin Lian asked.

"No, it's liquid butane. Come, hold it like this, and press down with your thumb. Wu Zhi taught her how to use it.

"No, it looks like it's going to bounce ......"

"Press hard."

Bang Bang –

Jin Lian successfully lit the lighter. Part of the flame is red, and part of it has a faint blue glow.

But just striking an artistic match? Fang Wen had never seen this kind of thing, so he took a box in his hand and looked at it: "Wu Zhi, how should this thing be opened?" ”

"Hahaha......" Jin Lian, Li Zhong and Sister-in-law Gu all laughed in unison, making Fang Wen laugh so much that the second monk was confused. After a while, Jin Halian's thumb was subconsciously loosened, and the flame was extinguished again.

Under Wu Zhi's reminder, Jin Lian pressed again.

In this way, a small lighter worth only a few cents was passed back and forth in the hands of five people, and everyone scrambled to feel the magic of this thing.

How exactly does it do it?

The five of them looked at Wu Zhi in unison, their eyes full of the same incomprehension and incredulity - it seemed that they couldn't wait to know the answer.

"The principle of the lighter is actually very simple, you see, it is in this place, there is a piezoelectric lighter, when we press the button, the piezoelectric ceramic will form a voltage, and trigger an electronic spark, thereby igniting the gas contained in the lighter, and then, the fire will be sprayed out of this opening, and this toggle switch, you can control the size of the flame......"

Wu Zhi held the lighter in his hand, and after explaining the principle of lighter ignition to everyone in a few words, he suddenly walked away a few steps and threw the lighter on the stone ground in front of the high ground.

Bang –

The lighter let out a thud and blew it up.

"Oh my God, what are you doing?" Li Zhong and Fang Wen rushed over, looked at the "corpse" of the underground lighter, and then looked at Wu Zhi, and were stunned......

"You're crazy, you don't want it, you can give it to us, why do you want to break this only lighter, oops, it's a pity......" Sister-in-law Gu also stomped her feet again and again, screaming pity.

Wu Zhi looked at the eyes of the two of them, and it was clear that Wu Zhi was violently destroying the heavens......

If Wu Zhi can't give them a reasonable explanation, I'm afraid they will kill Wu Zhi on the spot. Not to mention, at this moment, they really have this thought......

Wu Zhi walked over and peeled off a small black thing from the "corpse" of the exploded lighter, he was very excited, holding it high and showing the gadget to everyone: "Look, this is the piezoelectric lighter I just told you about......

"Wuda! You broke the lighter just to show us this?!!! Fang Wen was so angry that his body trembled, if he had kung fu like his sister Fang Qiong, he would have wanted to jump up and slam Wu Zhi's head with all his might, to make him sober up, what a useful invention he had destroyed!

"yes!" Wu Zhi replied innocently.

"Ahh Because he knew very well in his heart how valuable the lighter that Wu Zhi called was.

But Wu Zhi was silent, snapped, boom, and turned the baby into nothing, which is why Fang Wen has no anger.

"I'm going to strangle you!" Fang Wen shouted.

"Haha, the firer is gone, Fang Wen's anger has poured up, it seems that he is also an idiot......" Fang Wen was going crazy, but Wu Zhi laughed:

"Fang Wen, don't move. Don't underestimate this little thing, it's fun, when I was little, it was the best and cheapest toy for us boys for a while......"

"Toys?" Fang Wen was dumbfounded. In his eyes, this thing is more precious than the Night Pearl, but he said that it is just a cheap toy?

What Wu Zhi said was true. As a modern person born at the tail of the twentieth century and raised at the beginning of the twenty-first century, when they were children, sometimes in order to save money, children used their brains to figure out how to make something fun without spending money.
