After deciding on a solution, Chen Peng placed his backpack on a large rock near the shore, and then traveled lightly to the bamboo forest to choose suitable bamboo.

"In our Huaxia, everyone should be no stranger to bamboo rafts, in the past, the landscape paintings of the ancients can often see bamboo rafts floating on the river, and the anchor is estimated to be the kind of 'lonely boat' feeling, I don't know what everyone thinks, anyway, the anchor feels that the bamboo raft looks very poetic. ”

Chen Peng has walked outside the bamboo forest at this time, the outermost bamboo is generally the thickness that one hand can hold, it is obviously inappropriate to use this to make a bamboo raft, the buoyancy is not so great in comparison, but like some very thick bamboos are obviously not suitable, Chen Peng is now only one person, not only cutting bamboo is very laborious, but also it is very difficult to drag them to the shore to weave into a bamboo raft.

Bamboo can be said to be a very sentimental plant in our China, how many bamboo forest wise men and women in ancient times will live in the mountains and forests, bamboo shoots are also very delicious ingredients, last night Chen Peng's bamboo shoots pheasant soup it is a staple ingredient.

The principle that the bamboo raft can float on the water surface is actually very simple, the special structure of the bamboo makes it hollow between each section, they also have a very good airtightness, the weight is not large, the selection of materials is convenient, and it is not unreasonable for us Chinese people to use them as water vehicles.

Chen Peng walked a little further into the bamboo forest to find the bamboo that satisfied him, you can see that the diameter of a large piece of bamboo in front of him is almost between ten centimeters and fifteen centimeters, and it can also be described as the size of a bowl, which is currently the most perfect size of Chen Peng's bamboo raft made by a single person, and the length is usually three or four meters.

After choosing the bamboo, Chen Peng probably had an idea in his mind, making a bamboo raft in addition to bamboo also needs ropes and other things to tie them together, if only one bamboo is used, it is meaningless, it is better to swim directly across the river faster.

And there is such a thing as a rope, Chen Peng smiled at the camera and said: "Audience friends, the anchor has already chosen bamboo, and now what needs to be done is to cut them and bring them back to the river, I saw that there is a barrage that says that a rope is needed, that's right, making a bamboo raft naturally requires a rope, don't forget that the anchor has a backpack full of parachute ropes, and it's perfect to tie bamboo." ”

I patted the bamboo next to me, the bamboo forest in the rain always exudes a unique fragrance, and the sound of the rustling of bamboo leaves will have another taste if you close your eyes and listen to it.

Fifteen bamboos, this is the number that Chen Peng came up with after some calculations, if he wants to make his big one of more than eight meters successfully float on the water, it is impossible to do it without a bamboo raft more than one meter wide.

"Wait, fifteen bamboos may not be enough, if it is a single-layer bamboo raft, will it not be buoyant enough?" Chen Peng said with his chin on his hands.

The enthusiastic audience in the live broadcast room immediately responded to Chen Peng, have you forgotten this buoyancy calculation formula.

F float = G row = m row * g = ρ liquid * g * V row, where G row refers to the gravity of the discharged liquid, m row refers to the mass of the discharged liquid, ρ liquid refers to the density of the liquid, and V row is the volume of the discharged liquid (I believe you will recall the time when you studied physics in high school when you see this long list of formulas and explanations).

"Anchor, you can do the math. ”

"That's right, streamer, it's time to show your true level of physics. ”

"The people who eat melons have already brought a small bench to buy watermelons, and are waiting for the anchor to do crazy arithmetic. ”

The audience in the live broadcast room is obviously the type of person who doesn't have back pain, and the content on the barrage is more gloating, Chen Peng looked at the old man and blushed, when we were in high school, physics was okay, but after so many years, what a formula is this, and the reasoning has almost forgotten it.

"Okay! don't be so troublesome, the anchor has decided, just get two rows of bamboo, sink and pull down. Chen Peng coughed dryly to hide his embarrassment.

There are fifteen bamboos in the lower layer, then there must be fourteen bamboos in the upper layer, so Chen Peng will probably go down at least thirty bamboos, after all, the bamboo raft still needs a pole, and the bamboo raft can not be made by hand, after all, Chen Peng is not the kind of person who can row without pulp, I can sail without wind direction.

Chen Peng rolled up his sleeves and prepared to do a big job, when he squatted down to face the roots of the bamboo, he looked at the small dagger in his hand, and then looked at the hard roots of the bamboo brothers, Chen Peng was slightly stunned at this moment.

"Ahem, that natto, natto, do you have any saws or anything like that for me to saw? Chen Peng said with a flattering face.

Meng Meng Da natto hummed a little song and said: "No, did you tell Ben Meng Mei in advance, if you say it in advance, Ben Meng Mei can also consider helping you make a saw, who told you not to say it earlier." ”

Chen Peng has a black line, and he doesn't know how to cross the river to make a bamboo raft, but since his flags have been erected, this force must be installed no matter what, after all, there are 600,000 viewers watching him in the live broadcast room now.

Click, click!

For more than an hour, the monotonous sound never stopped, and Chen Peng was stunned to cut out thirty bamboos with a small dagger, during which Chen Peng had to drag them all to the river, which was really a very time-consuming and labor-intensive project.

"Huh~ It's really tiring, my old waist is about to break, you can see that every bamboo the anchor gets is not easy, not only is it difficult to cut, but when they finally fall, the top of them will always be entwined, and they can't be dragged together. ”

Chen Peng wiped a handful of sweat, although the process was hard, but his face was full of smiles at this time, looking at the thirty bamboos lying in front of him now Chen Peng had a sense of pride in his heart, this is me with a small dagger to cut it out one by one, it is very awesome Okay, and it is not enough to cut them down, they must be pruned, and the scattered branches must be removed.

When Chen Peng cut bamboo, the audience in the live broadcast room did not send less bamboo, and the god of Ceres did not send Buddha to jump over the wall at this time, all of them were 6666 bamboos to brush the screen, and in just such a while, the height of Chen Peng's live broadcast room soared directly to more than 100 meters.

"The next thing is to weave a bamboo raft, this is also a big project, roll up your sleeves and do it!"
