Chapter 496 Jumping Battery

How can you jump higher without emptying yourself?
Baitang accidentally dropped two charged batteries into dozens of identical empty battery piles. If he wanted to find these two batteries, he would be looking for a needle in a haystack.

But the good thing is that Fan seems to have thought of something.

Yu Fan: "We have to use chemical methods."

Chen Xiangyang suddenly understood something: "I remembered, I heard a big guy say that the new battery is soft, the old battery is hard, the new battery is heavy, and the old battery is light. You can feel the difference with your teeth. "

Guo Na complained: "Brother Chen, are you planning to leave your tooth marks on these dozens of batteries? Then if some batteries leak, you will be poisoned, it is not easy to rescue here."

Chen Xingyang: "Then what should we do? Old Yu, isn't that what you said?"

Yu Fan: "Uh... Indeed, there are some differences in weight, softness and hardness between old and new batteries, but what we want to use is another method, using another chemical characteristic."

Baitang: "Brother Yu, tell me quickly, don't keep it up, Brother Zhang will be back in a while."

Yu Fan turned on the science popularization mode: "It's very simple. First, hold a battery in each hand and keep it at the same height, 30-40 cm away from the table. Then release both hands at the same time and let the battery fall naturally. Then, we It can be seen that some batteries will bounce up, but some will not or are very low, then we can judge the old and new batteries at this time. Generally speaking, the battery that does not bounce high after falling is a new battery, and the one that jumps more High ones are old batteries."

Chen Frameyang: "Why?"

Yu Fan: "To put it simply, the new battery has a semi-liquid substance, which is cushioned and cannot jump up or jump high. When the old battery is dead, the alkaline substance in it is gone, but it will produce some Gas, so a low or dead battery jumps up after falling."

Guo Na concluded: "Understood, the ones that can bounce are empty batteries, and the ones that can't bounce are new batteries."

Everyone immediately tried it out.

Sure enough, in a few seconds, everyone found the new batteries mixed in the old battery pile, put them back in the flashlight, put the flashlight back in the drawer, and closed the drawer, as if nothing happened.

Chen Xingyang, Guo Na, and Bai Tang laughed and celebrated there.However, Yu Fan vaguely sensed something was wrong.

Yu Fan simply calculated the power consumption of this flashlight. Two batteries can be used for about four hours.The batteries in this drawer meant that the flashlight had a cumulative operating time of perhaps two hundred hours.It has been about a few months since the construction of this temple started. Even if Zhang Zai is the first group of believers to come here, it means that Zhang Zai has to turn on the flashlight for at least two hours every night!Moreover, the power consumption of the flashlight was just an estimate. If the weak current effect is included, Zhang Zai would have to turn on the flashlight for three hours every night!
What did Zhang Zai do during the three hours of the night?reading?But Yu Fan had carefully observed the room just now, except for a military magazine, there was no book in the room.

Yu Fan couldn't figure it out, he didn't know where Zhang Zai used the "electricity".Maybe these batteries aren't just for flashlights?Or maybe Zhang Zai put the book he finished reading somewhere else?All this is unknown.

"I'm back." Zhang Zai moved quickly, and he had already returned to the tent door with a few quilts in his hands.

Baitang went to the tent entrance to help Zhang Zai pull up the curtain of the tent, and Zhang Zai walked in unsteadily.

Zhang Zai said with a smile: "The conditions are rather harsh, so fellow Taoists, we will just settle for it. We are all practitioners, so I believe you will not mind this. The quilts I selected are all Taoist friends who love cleanliness. "

"Boom~dong~" There was another powerful bell from outside the tent.

Baitang asked curiously: "Is this the Fa conference about to start?"

Zhang Zai nodded: "Yes, this afternoon is the chanting session. But, we don't have to go, because we will go to the construction site to get some wooden boards on the ground to prepare for going to bed at night. I will take all these wooden boards It's not easy to get people. I need your help."

Chen Frameyang: "Zhang Daoyou, you are so polite, this is what we should do, thank you very much."

Zhang Zai: "Then let's leave now."

The five people got out of the tent, and saw that the believers in the tent group also got up and walked towards the main hall. Many people directly opened the curtains of the tents and left them open.

Chen Xiangyang asked Zhang Zai curiously: "There are so many idle people living here, and the curtains of the tents are also open. Do you often lose things here?"

Zhang Zai said with a smile: "As far as I know, I have been here for a long time, and there has not been a single incident of theft here. Everyone is still very conscious."

Guo Na: "People with faith are really powerful."

Zhang Zai shrugged and said, "Actually, I don't think it's a matter of belief or not. The main reason is that people who come here don't bring any valuables. Fellow Taoists don't need to ruin their merits for these small money."

Yu Fan: "Then what if it's not small coins, but valuables?"

Zhang Zai: "No one can resist these temptations. Small money can't shake people's hearts, but if there is a huge sum of several million here, I believe some people will risk their lives to steal it. .”

Baitang: "Brother Zhang, will you do the same?"

Zhang Zai said seriously: "Everyone is like this, you have to admit this fact. However, I will not put myself in that embarrassing situation."

Yu Fan: "What is an awkward situation?"

Zhang Zai: "A real veteran driver does not walk the tightrope all day without overturning the car, but never drives on the edge of the cliff at all. A real practitioner should not always put himself in a situation full of temptation and danger. Put yourself out of the world!"

Yu Fan admired this young man named Zhang Zai from his heart. Compared with other believers, he seemed more rational and understood more thoroughly.

The five people went to the construction site to search for some moisture-proof materials. Although they didn't find wood boards, they found a lot of thick cardboard, which was enough for them for the time being, because they didn't want to live here permanently.

After dragging the cardboards back to the room, it was almost four o'clock in the afternoon. Zhang Zai hurriedly left and went to prepare dinner. After all, for him, apart from his identity as a believer, he also had a more important role as a cook.

After Zhang Zai left, Guo Na took out his mobile phone.Today, taking advantage of everyone not paying attention, Guo Na recorded all the people here one by one.

Guo Na: "Let's take a closer look, is it true that there are no Baitang's parents? There is no Zuo Cequan?"

Chen Xingyang: "If it's really not there, we don't need to stay here anymore, let's go back tomorrow."

Just as everyone was discussing the next step, the melodious flute suddenly sounded outside the tent.

Strange, aren't believers attending the Fa conference at this time?Who would play the flute outside so leisurely?
