Liu Wei: "Facing such a big electric eel is a very stressful thing. I must operate the next experiment carefully, otherwise my life will be in danger!"

The foam boxes were carried ashore.

Master De prepared the equipment.

Liu Wei reached out to catch the electric eel, stretching his hands very far to prevent the electric eel's body parts from touching his body.

The electric eel seemed to be very confident in its abilities. When Liu Wei grabbed it out of the box, it didn't struggle too much.

"No! Damn it~"

As soon as he placed the electric eel on the film, Liu Wei stopped his hand instantly and his whole body trembled a few times.

From the heart to the whole body, all kinds of discomforts seemed to be twisted together by a force.

"Liu, are you okay?" Mr. De asked with concern.

Liu Wei calmed down for a while and nodded, "My gloves seem to be soaked in water. The stinging sensation caused by the current just made me very uncomfortable!"

Mr. De took off his gloves and handed them to Liu Wei.

Liu Wei checked again and again to ensure that no more accidents could happen.

Every time I try, I risk my life.

After making sure that the gloves and hands were dry, he took out a tape measure and measured the electric eel's body length. "2.14 meters, that's great, brothers. According to scientists' research, the amount of electricity released by this electric eel must be surprising!"

He looked at each other.

The two nodded.

"Come on! Liu! Be careful!" Master De ordered.

Liu Wei bit his lower lip and held electrodes in both hands close to the head and tail of the electric eel.

"呲呲呲呲~"

"Are you ready? Master De!" Liu Wei let go and raised his head to ask Master De.

Mr. De looked at the meter of the power regulator and became distracted.

"Master De!"

After shouting several times, Mr. De came back to his senses and shook his head, "Liu, it's too scary! Look at the amplitude of this current!"

The instrument shows that the moment the current is received, the voltage reaches its peak and the amplitude approaches vertical.

Liu Wei stared at the peak value on the instrument for a while, then turned back to face the camera seriously and said, "Brothers, its discharge voltage has reached 833 volts!"

"????"

"Fuck~"

"It's so scary! The dog head saves his life!"

"You can make the hair on my legs burn with electricity!"

"Killed instantly!"

The audience was amazed.

Liu Wei: "The voltage of 833 volts is enough to stop the heartbeat of an adult crocodile or a strong buffalo in a short time.

Death from suffocation. "

As he said that, Liu Wei couldn't help shaking his body, "Master De, let's put it in the box first! We can't let it run away.

Have you ever eaten electric eel meat? I heard it tastes pretty good! "

Mr. De smiled and shook his head.

Liu Wei smiled and said: "That's it for dinner today!"

Before deciding to eat electric eels, Liu Wei still had a very important thing to do, which was to learn more about the discharge principle of electric eels.

This is also the most curious question from the audience.

Facing the live broadcast camera, Liu Wei said seriously: "Now it's time for professional science popularization. You may only be able to see the following science popularization content in world-class scientific documents such as SCI, so interested viewers can start writing!"

"Write it down for the test!"

“I like listening to Ah Wei’s professional knowledge the most, even though I don’t understand it!”

“The nine-year compulsory education qualification sounds awesome!”

Liu Wei said: "The question that everyone is most interested in should be why do electric eels discharge?

Before popularizing the principle of electric eel discharge, we trace the history back to 200 million years ago. The latest research results of American scientists on electric eel power generation show that electric eels first evolved the ability to charge 200 million years ago.

In other words, during the Carboniferous Period 200 million years ago, electric eels were already able to release electric current through their bodies. Since then, the electric eel's power-generating organ has evolved six times, gradually forming its current perfect discharge organ. "

"Two hundred million years ago? It's actually still alive!"

"You can tell by its appearance that this thing belongs to an ancient creature!"

"The electric eels from 200 million years ago should have been bigger! There was no human activity at that time!"

"Look now, apart from humans, electric eels should have no natural enemies!"

Liu Wei went on to popularize science: “Based on long-term scientific research, it has been determined that the source of the electric eel’s discharge ability comes from the discharge body composed of its specialized muscle tissue.

The muscles on both sides of the electric eel's tail are composed of 6,000 to 10,000 muscle lamellae arranged regularly, with connective tissue separating the lamellae and many nerves leading directly to the central nervous system.

The head of the electric eel is the positive electrode, and the tail is the negative electrode. Each muscle sheet is like a small battery, which can only produce a weak voltage of 150 millivolts. But when nearly 10,000 of these small batteries are connected in series, the voltage during discharge can be as high as 600~ 800V or even higher. Just like the electric eel in front of us, when discharging, the peak voltage reaches 833 volts. However, this high voltage can only be maintained for a very short time, and the discharge ability will weaken with the fatigue of the body.

It needs to rest for a period of time before it can release high voltage under extreme circumstances! "

"That's enough, it only takes a few seconds to kill someone!"

"I wonder if I should get an electric eel?"

"Brother, your idea is dangerous!"

"It's best not to avoid hurting other people in the family!"

Liu Wei: "The breeding conditions for electric eels are very harsh. If you are not familiar with this type of creature, I do not recommend that you raise them.

Electric eels have no teeth and rely on suction from the mouth to suck food into their mouths, so keepers need to be very careful when feeding.

After talking about the principle of electric eel generating electric current, let's take a look at its discharge process.

To sum up simply, it can be understood that the innervated cell surface has the function of nerve-controlled ion channels. When the channel is innervated and opened, a large amount of cations flow out to form a voltage, while the other side is a non-innervated sodium pump, so it can slow down Slowly pump the cations back into the cell to prepare for the next discharge. With countless cells arranged in such a plate-like manner and firing in the same direction, the voltage can reach considerable levels. "

"oh!"

"???"

"I suspect the host is insulting my IQ!"

"speak English!"

"I seem to be able to understand! Am I too well educated?"

"Bah~, shameless, please leave the live broadcast room!"

Liu Wei: "It doesn't matter if you don't understand. The research results on electric eels have been accumulated over many years. If you are interested, you can study the physics knowledge about electric current after you go down. It will not be difficult to understand it when you come back."

Then Liu Wei put another small electric eel caught by the villagers into the same foam box. There was no conflict or friction between the two electric eels and they got along harmoniously.

Liu Wei smiled and said: "Is there another problem? I know everyone must be curious, why don't electric eels of the same kind produce electric shocks?

Because the fat tissue in the electric eel's body has a very good insulation effect, and after 200 million years of evolution, the electric eel's body has adapted to a weakly charged environment. We just mentioned that under normal circumstances, the electric eel will not release strong electricity. , so electric eels of the same kind can live harmoniously in the water. "

"I also have a lot of fat, but it has no insulating effect!"

"Maybe it has a warming effect, hahaha!"

"No, no, no, maybe it has a conductive effect. If you don't believe me, go back and touch the wires to try!"

Liu Wei reminded: "Brothers, please be polite and don't joke around. I remember that the president of a certain country proposed the idea of ​​drinking disinfectant, which harmed many people!"

"I know this president, hahaha, he came from Deyun Club!"
