Outside the laboratory, Wells was waiting at the door with two followers. Wells warned viciously: "You are ready for me later. As long as this guy is bluffing with us and can't get the battery out, you can rush in and teach him a lesson. Do you know? Fill water, soldering iron, pulling nails and other things on it!"

The two followers nodded together: "Understand, don't worry, I guarantee that I won't let you down. . Updated the fastest."

Time passed by minute by minute. Wang Hao, who was in the laboratory, ate and slept well. He rested until three o'clock in the afternoon before he woke up.

When the person in the monitoring room saw Wang Hao wake up, he immediately reported: "Wang Hao is awake and can enter."

"Mr. Wang Hao," Wells asked politely outside the door: "How are you resting? Can we come in?"

Wang Hao lay on the bed and put on a very comfortable position, saying, "Come in."

Soon Wells walked in with two followers and smiled, "Mr. Wang Hao, do you think when will we start?"

The maid was pounding Wang Hao's legs and occasionally feeding him a sip of red wine.

"This is the beginning," Wang Hao smiled, took a sip of wine with satisfaction, and said, "This time the battery is relatively simple, I guess you should be able to make it with your IQ. Of course, if I can't do it, I can't do it anymore. In that case, you might go back to elementary school and study again."

"Yes, yes," Wells asked hurriedly: "Then Mr. Wang Hao, what raw materials do our batteries need this time? To be honest, I don't understand..."

"This time it's simple," Wang Hao began to place an order for Wells: "You can prepare three lemons first. If not, limes, apples, pears, and pineapples are also fine. Can you understand this?"

Wang Hao understood what Wells was talking about, but he was still confused.

"Mr. Wang Hao," Wells asked, "Do you want some after-dinner fruit?"

"I'll eat your hammer!" Wang Hao was furious in an instant: "If you ask you to do it, go and do it, why don't there be so much nonsense?"

Wells was embarrassed, but there was no way. He naturally had to agree when he spoke. However, when he asked his men to get these things, Wells greeted Wang Hao's entire family's immediate relatives in his heart...

Soon the fruit was brought over, and it was actually three lemons.

"The next are three bright copper coins." Wang Hao continued to issue an order: "Just use a five-cent coin. If there is really no copper sheet, copper pieces can be used. Copper, do you know this?"

Wells was confused, but nodded: "I know."

"The next are three galvanized screws," Wang Hao continued: "There are four more wires, preferably with clips on the wires to clamp the copper coins and screws."

"What are you going to cross?" Wells was confused again: "That doesn't seem to be there..."

"Are you a refugee camp?!" Wang Hao wanted to get up and kick him and told him to know what basic chemistry is: "If you don't have zinc, use aluminum sheets! Do you know about aluminum sheets?!"

"This knows this knows this," Wells Falls Khan nodded quickly: "This has!"

Wang Hao thought for a while, and then said, "Then there is a small knife and a small paper sticker label. The low-voltage-driven light-emitting diode is the light bulb. Do you understand the light bulb?"

If the light bulb doesn't understand Wells can die. He nodded desperately: "I understand!"

"Finally, prepare a black opaque film shell." Wang Hao continued: "This is used for light-shading, easy to observe, and then a nail or a small awl is used to drill holes in the light-shading container."

Wells could understand these things. He hurriedly asked his subordinates to prepare everything. Wang Hao then began to teach them how to do it: "First make the lemon softer, the softer the better, so that it is to make more juice inside the lemon. This step is very important, because in this way, the best effect of the lemon battery is achieved."

"Wait, lemon battery?!" After hearing this, Wells shouted loudly: "Are you sure you are right? Lemon can be used as a battery?!"

"Are you an expert or I an expert?" Wang Hao wanted to kick him again: "You can just do whatever I say, otherwise if the experiment fails, yours will be mine?"

"Yes, yes," Wells muttered while rubbing the lemon: "It's a lemon to make a battery? What a joke?"

Although he was full of disbelief, Wells still did as he did.

"Okay, next, that aluminum sheet," Wang Hao continued to direct Wells: "Insert one-third of the lemon, then use a knife to cut a one-centimeter incision on the other side of the lemon, then insert the copper sheet into the incision and insert half into it."

Wells was done quickly and asked, "That's all?"

"Yes," Wang Hao nodded: "Do you do this with the other two lemons later."

Soon all three were done, Wang Hao continued: "Now, the copper sheet is its positive electrode and the aluminum sheet is its negative electrode. Next, use wires and clips to connect the aluminum sheet on the first lemon and the copper sheet on the second lemon, so that the three lemon batteries are connected together, and at the same time, the first and last aluminum sheets are connected with wires with clips."

"Okay, OK," Wells said excitedly, "What's next?"

"Next, get the light bulb you prepared..." Wang Hao looked at the two hundred-watt light bulb that Wells took out and roared: "Are you a pig?! How much current do you think this thing can have? Change the small light bulb! Do you understand the small light bulb?! It needs the smallest one!"

"I... Isn't it better?" Wells ran out to change the light bulb and quickly got back the smallest light bulb. The small light bulb looked only the size of a small fingernail, probably only about one or two watts.

"It's almost the same," Wang Hao nodded with satisfaction this time, and said, "Now you drill the hole in the black film shell and put the light bulb and wire in to observe it, do you understand?"

"I understand," Wells excitedly said, "and then power on?"

"Or else would you ask you to eat lemon?" Wang Hao hummed and drank a sip of wine: "Is it bright?"

Wells looked inside the film shell with curiosity. At first, he was full of disbelief, but after seeing it, he jumped up!

"It's bright! It's really bright!"
