Levi hadn't thought about it at all. He simply thinks that everyone still has a good chance of success, and there is no need to give up so early now, wasting all the effort before.

"If we can find a way to fix the line where the drums roll down, then we can really reduce the amount of salt used, and we only need to sprinkle salt to pave a 'road' that is enough for the drums to pass. However, the snow is uneven everywhere, and the degree of solidification of the snow itself will also change the coefficient of friction, resulting in different friction forces from the various 'parts' of the snow when the bucket rolls down. Even if the snow is flat, like a freshly paved highway, it is still difficult to ensure that the bucket will not deviate from the 'track' halfway through the straight line. ”

The more I listened to her, the more I felt that Miyuki didn't look like a normal high school girl. It's not a matter of sexism or anything like that, but a girl's hobby should naturally have things like fashion and literature that make her beautiful on the outside or inside. The knowledge of friction coefficient is actually a concept that everyone has learned in school. But those who can flexibly apply them to real life, not to mention girls, there are very few boys.

Although the purpose of education is initially to equip children with knowledge and skills that can be used flexibly in their future lives. However, education has been radically changed from that basic concept a long time ago. It has evolved into a 'classification method' that is supplemented by teaching children useful knowledge and skills, but is mainly more convenient and simple to select talents in the future.

"It's hard to get this bucket to roll straight down the hillside every time. But didn't you just say that in the TV show you saw at the beginning, the people in it made ice cream by putting tea cans on ice cubes and rolling them around?

Miyuki Takara, and Yagami Speed, the two girls who were asked by Levi, nodded together. However, these two girls who are originally very smart, especially those who have always excelled in their respective fields, have not understood what Levi wants to express until now.

Seeing that the girls were still looking ignorant, Levi couldn't help laughing unexpectedly, and then directly told them the way he thought of: "Since that's the method used on TV." So why don't you just imitate the TV show, like digging a hole in the thick snow and putting a bucket in it so that you don't accidentally let it roll. And then we all work together to get it going back and forth in the pit? If it's just a snow pit, you should be able to buy about enough salt at the resort, right?"

"That's ...... Doesn't sound like a problem, do you think it's possible?"

Xiao Jing held his chin and thought about it, and tilted his head to poke Takara Miyuki on the side.

"Of course, it's the same as on TV, except that the container is bigger and the amount of ice used is increased, just like baking a huge pizza in a huge oven that can be eaten by a lot of people, at most it takes a lot longer, but it should be successful. ”

Miyuki replied affirmatively, and then explained: "Actually, this method is the most secure. The reason why I didn't use it at first was that I discussed it with this party at the time, and I thought it would be more interesting to push the bucket up and let it roll down on its own. I didn't expect to waste so much effort in the end, I'm really sorry. ”

Said Perfect Yuki and bowed to everyone apologetically. And of course, everyone can't really have any dissatisfaction with Meixing because of this, and quickly help her up to comfort each other. Bian Shangquan looked at Mei Xing like this, and he finally felt that it seemed to be a bit of a toss to everyone, and then he also came out to apologize. A group of girls just like this, you apologize and I don't need to push around, Levi obviously came up with a good idea and ended up hanging aside, but seeing that these girls have such a harmonious relationship, he naturally won't be stupid and bored.

"So, if you do what the teacher just thought, we can make ice cream, right?"

Ah, Naye has really not changed after many years, and she is a lively and lovely little angel like back then. You see, even Lévy's favorite good daughter, Fett, didn't say a word, and Naye immediately remembered him. If it weren't for the presence of the Hiiragi sisters and Miyuki Takara, Levi would have to worry about the impact, and now he would like to pick up Naye and rub her little face to thank her!

Of course, no matter how Naye hasn't changed, it's not the double ponytail Lori of the year. Naye, who has grown into a slim and beautiful girl, if Levi is hugging him like he did when he was a child, the picture may indeed look very bad, and his worries are not superfluous at all.

"Yes, you can do that!"

"Okay, then I'll go buy salt now, you guys wait a minute!

Receiving an affirmative reply from Miyuki again, Naye took Fit's hand and ran towards the resort as before. But this time no one stopped her like just now, but Xiaojing seemed to feel embarrassed to always let the school girls pay for the ingredients, and when she beckoned and wanted to call Naye, she found that the girl who was full of vitality had already pulled Fitt out and ran out quite a distance. I had to put down my hand again and hold back what I wanted to say. But it seems that Xiaojing has made up his mind to calculate the money for the ingredients and raw materials after returning to the hotel, at least he has to give his share, or as a senior senior sister, it will be difficult for this tsundere girl who loves to drill the horns to pass this level in her heart.

"That's, that'......"

Everyone watched as the shadows of Naye and Fitt on the snow became smaller and smaller, and suddenly Xiao Si raised his hand and opened his mouth hesitantly.

"Xiao Si, what's the matter with you?"

After all, it was her own sister, Xiao Jing looked at Xiao Si and thought she was uncomfortable, so she took her hand and looked up and down, wanting to see if there was something wrong with her.

"Sister, I'm not feeling sick!"

In front of so many people, let his sister stare at him like this, Xiao Si was embarrassed to shake off Xiao Jing's hand, and his face turned red. But in fact, Xiao Si's face was a little red before, and the red spots are not obvious now. It's probably like eight ripe shrimp that are finally fully cooked after boiling them again.
