Sweet 80s

The two children had a lot of things to do tonight.

Wait until the prelude is almost done.

Just when Erbao was playing in a daze, Dabao pointed at the toy on the ground and said, "The tin frog has jumped over there, go and get it out."

Then, Dabao pointed in the direction of the clay pot where the pickled eggs were.

Erbao ran over obediently without any precautions.

Following the gap between the jar and the wall, he saw a hint of green, so he reached out to take the frog out.

Woof woof woof.

Dahuang barked and kept nudging Erbao with his mouth, reminding him not to touch the jar.

Erbao didn't understand why, so he started to yell and shout and drove the boy away.

The clay pot had a thin neck and a thick belly, and Erbao's hand got stuck halfway through its insertion, making it impossible for him to put his hand completely in.

"Brother, come and help me."

Hearing his younger brother's request for help, Dabao pretended not to care and spoke to Erbao in an impatient tone.

"Why don't you just move the jar?" Although it was of no practical help, Dabao still secretly squinted his eyes to observe the progress of the situation from time to time.

Children are children, they look at any problem with a simple perspective.

Lots of ideas, but not much brains.

Dabao completely ignored a very realistic problem.

The weight of the clay jar itself, plus the total weight of 20 kilograms of eggs filled with it, each of which is wrapped in wood ash.

For a 5-year-old child, it is impossible to move it.

Erbao wrapped his hands around the can and after exerting force just once, the can didn't move at all. He gave up trying to move it and asked his brother for help again.

Dabao walked over very reluctantly. He knew that if the tank was damaged as soon as he touched it, he would not be able to escape unscathed.

He looked at the clay pot, then looked at his brother who was even thinner than the pot, and rolled his eyes.

"Then don't want it."

When Erbao heard this, he became unhappy and turned around to run into the house to ask his parents for help, but was stopped by Dabao.

"Wait a minute. How about this, hiss~, you squat down and hold it, and see if you can move it."

At this time, Erbao had actually realized that something was wrong.

Because Dabao, as his older brother, is obviously stronger than himself, but he doesn't want to take action no matter what.

Although he couldn't figure out why in his little head, he still did as he was told.

Erbao squatted down, with his short hands only holding one-third of the can, and his head pressed against the mouth of the can. Dabao behind him was in the other's blind spot.

Just when he was about to exert force, Dabao took advantage of his unpreparedness and pulled the can mouth to another position and dragged it back, moving the can a few centimeters away from the wall.

The space is not wide, but it is enough to take out the tin frog.

Dabao looked at the damaged area and found that the broken pieces he had pieced together with his own hands remained in their original state, with no sign of falling off.

this...

This is like trying to fish for the moon in the water - a waste of time and to no avail.

Dabao pouted and frowned, and said to Erbao who was about to leave: "Push the jar back, or our mother will scold you if she finds out."

After hearing this, Erbao put the frog on the ground, put his hands on the jar, took a deep breath and pushed it forward with force.

In fact, whether the pushing and pulling forces are the same depends on many factors.

Although both will produce elastic force on objects, there are still differences in the final analysis.

For example, the vibration frequency and direction are completely different.

As the two children pulled the can outward, most of their strength was put on the top of the can.

When pushing back, the direction and point of application of the force are basically all concentrated at the bottom of the tank.

This changes the friction between the jar and the ground and the frequency of vibration.

When the creaking sound stopped, Dabao quickly observed the condition of the bottom of the tank, and his own paving design was finally completed smoothly as planned.

A very subtle "click" sound was heard.

Erbao didn't hear anything at all. Dabao stepped forward and grabbed his arm, pointing at the bottom of the jar: "Look! You broke the jar..."

Erbao stretched his head to take a look, and was immediately shocked and broke out in a sweat. He stood there in a daze, not knowing what to do.

Dabao ran into the house and told Wang Shuping the whole story.

When the couple came out, Erbao was blinking in confusion.

Wang Shuping leaned over to take a look, and was glad that it was not the pickle jar with soup in it that was broken.

"He just pushed it, it wasn't intentional, really, I saw it all..."

Dabao pretended to excuse his brother.

Wang Shuping touched Erbao's head and said with a smile: "It's okay, the jar is broken, just buy another one. Be careful next time when you touch fragile items."

"Ah."

"Go play, I'll clean up."

"Ok!"

After the two children left, Lin Xiangdong squatted down, picked up the fallen fragments and observed them carefully.

"The jar felt quite thick when I was washing it, but how come it broke just by pushing it? The quality is too poor. Such a good jar is wasted..."

After Wang Shuping finished complaining, she prepared to take out all the spoiled eggs.

"It wasn't Erbao who broke it." Lin Xiangdong looked back at the two children in the distance and said.

"Ah? What do you mean?" Wang Shuping asked.

Lin Xiangdong took the fragments in his hands and fiddled with them for a few times, speaking with wisdom and composure in his demeanor.

"Anyone who has served in the army has most likely fired live ammunition, and you can see obvious bullet marks on the broken parts."

"What...what traces?" These words were too professional. Moreover, an ordinary clay jar was actually related to the bullet. Wang Shuping did not understand.

"An impact mark is a mark left when a bullet hits an object."

"Bullets? Where do the bullets come from?" Wang Shuping laughed helplessly twice.

"It wasn't a bullet. It was shattered by a small, fast-moving object. It can't be broken by just moving it."

While talking, Lin Xiangdong found a small stone from behind the can: "Look, the tool used to commit the crime."

Wang Shuping looked at the bullet in Lin Xiangdong's hand, thought for a few seconds, and then said in surprise, "Was it shot by a slingshot?"

Lin Xiangdong nodded affirmatively: "Don't underestimate the power of the slingshot. Replace the stones with steel balls. With a little more speed and force, these jars can be directly penetrated."

Wang Shuping frowned suddenly, thinking of Ji Xiaoguang who came to play with Dabao at noon: "They must have been playing with slingshots in the yard while we were not at home."

"I was wondering why he suddenly spoke up for Erbao. He used to just stand aside and watch the fun..." Lin Xiangdong's anger was already brewing.

No matter what time it is, don't talk too much, don't delay things, and don't act rashly.

Facts have once again proved that the more you talk, the more mistakes you make; the less you talk, the fewer mistakes you make.

Lin Xiangdong's face gradually darkened, his brows furrowed, and his eyes became stern.

"I usually threaten to beat him, but he never lifts a finger. Now look what has happened. He has become a bad person."

As he spoke, Lin Xiangdong rolled up his sleeves, looking like someone who was not to be trifled with.

"This kid not only pushed the responsibility onto his brother, but also played tricks on us. He is really getting more and more outrageous. Let me see how I deal with him..."

If I really start fighting when I'm angry, I'm afraid the child will be hurt.

"Hey, wait a minute." Wang Shuping stepped forward and held his arm: "Don't worry, I'll find some time to talk to him first."

"Okay, but if he gets angry with you, don't indulge him anymore."

"Ok, I know."

Wang Shuping understood her son's personality. He was not a bad kid who lied. He was just playing tricks because he was afraid of being beaten or scolded.

But she hasn't had time to reason with Dabao yet.

The next day, Monday, when school started, Dabao came back with even bigger trouble.
