Not to mention how heavy this iron bucket weighs when it is filled with ingredients, just the shape and volume of this iron bucket make it difficult for these girls present to keep rotating for a long time. After all, in the TV shows that Miyuki Gao Liang has watched, people only use small tea cans, and it is not too tiring to pinch and turn a few times with his fingers. However, if you want to turn this big iron bucket, you can only grasp the edges of the front and back, although there is a small circle of protrusions in that place, but in the winter when the frost is frosty, it is slippery and does not leave your hands, and it is estimated that it is difficult to hold and exert force. From this point of view alone, the method that I thought of before really felt that it was relatively easy to do. If you can get enough salt, for example, some cities will go out early in the morning in winter to spread salt on the main road and pop the snow plows and so on, maybe they will have succeeded in this idea.

"Senior Sister Gao Liang, I want to ask a question. ”

Fit was dragged by Naye to buy salt, and the remaining Yagami Blast, the rest of the three magical girls, had been quietly serving as a background board in front of several senior sisters just now, and when everyone was distressed at this time, she suddenly appeared.

"What's the problem?"

Although Mei Xing, who is a good teacher, is thinking hard about the current solution, this good-tempered senior sister who feels like she will never get angry will naturally not let her senior sister shut up or anything.

"I wonder if the reason why the ice cream making method requires the container of ingredients to be rotated on the ice cube is actually the same principle as the machines in the shops that sell soft ice cream?"

The kind of machine that Hurricle is talking about, everyone knows what it is as soon as you hear it. In those shops where you buy ice cream desserts, you can put a cone or paper cup under one of the openings of the machine, and then press a button to automatically run out of soft and smooth ice cream. The machine itself has a structure similar to a washing machine, constantly rotating and stirring the ice cream inside, which does not need anyone to popularize science, everyone knows that it should be to keep the ice cream inside in a soft ice cream state, not to solidify into a cup of ice cream that is closer to the solid.

"Well, there should be similarities in principle, but it's not exactly the same. The reason why it has to be rotated all the time, just like the purpose of the machine, is to prevent the milk and cream in the container from curling too hard. If it doesn't rotate, stir or mix in without air, and when the milk inside freezes, it is estimated that it will be a large piece of ice made of milk and custard. But we're not trying to make soft ice cream, as long as it's like a cup of ice cream. I don't think we can make soft ice cream just by turning the bucket outside instead of mixing it inside like that kind of machine. ”

In fact, the specific principle was not explained in detail in the TV show that Miyuki Takara watched. After all, it's just an interesting program like a little common sense of life at noon, and it won't take out all kinds of details for analysis and research like those popular science teaching documentaries. Miyuki was asked by the wind, and she could only try to answer it with the knowledge she had learned before.

"In other words, the purpose is to prevent the milk and cream from freezing into ice cubes, right? Doesn't it have to turn the bucket 360 degrees like a tire, just let it move at a relatively large margin? For example, turn half a circle to one side, then turn back and then half a circle to the other side, like a pirate ship in a playground?"

The pirate ship in the playground is not actually called 'turning' but should be 'swinging' or 'swinging', but except for the wide-eyed and stunned Xiao Si, everyone knows what the wind is talking about.

"I haven't tried it, but I think it should be okay. As long as the amplitude of rotation is not too small, it does not have to be rotated 360 degrees to allow enough air to mix in. ”

"In that case, let's find a rope and tie it to the iron bucket, and then everyone pulls it from both sides, which should save a lot of effort. ”

Hurricane added, "I've seen it on TV before, and I remember it was like a wilderness survival show. At that time, the contestants in the show used this method to extract the bottom water. ”

A few seniors nodded frequently at the words of the junior, but Levi knew about that TV show, and this girl was made up improvised. The method she was talking about was not something that ordinary people could do, and it sounded like it was easy to tie an iron bucket with a rope and then pull it on both sides and turn it. However, not to mention such a large iron bucket filled with liquid, whoever thinks that it can be done, go home and find a cup without a handle or something like that, try it yourself, and see if it is as simple as you imagined?

It can be easily and easily turned with a rope, which must be tied with a special technique, tied with a fixed dead knot on the iron bucket, and then wrapped around a movable slipknot. And in order to save effort easily, the tying of several knots and the position of each other are also quite particular. Ordinary people have not undergone special training, and they may not be able to get the kind of effect that the wind said for a long time just by thinking about it on their own.

Generally, those who can master this knotting technique are first of all those who have served as soldiers, or similar to the 'scouts' popular in some foreign countries, and secondly, those who are keen on outdoor orienteering, or rock climbing and mountaineering.

The Temporal Authority, to which Tempest belongs, sounds more like a law enforcement agency like a policeman, but is actually a more violent agency like the military. This can also be seen in the adoption of the military rank system within them. Working in that kind of organization, it's not much of a problem to say that the wind is half a soldier.

Although the number of times she has been on the front line is far less than that of her other two friends, Fitt and Naye, she has been planning to prepare for the 'special unit that belongs to everyone'. Although the previous Hurricane was too powerful and difficult to control because of the magic he was good at, he often intervened on the battlefield when the situation was at the most critical or when he entered the right stage, but this did not mean that the basic battlefield and wilderness survival skills that other colleagues had mastered, and Hurricane had not studied and practiced as well as others.

Despite being magical girls, the magic mastered by most of the people in the Space-Time Authority is primarily combat-oriented. Even if some personnel are not good at magic that directly exerts combat power, it is also auxiliary combat magic that assists combatants to exert higher combat power. They are not like some magicians on this earth, who use magic to do everything in their daily lives that ordinary people cannot do, or that are more troublesome and difficult.
