Anyone who has watched martial arts movies has a question: Are the scenes inside real? We see someone flying on water, can that person really fly? Someone specifically tried, but it didn't work out. Even the warrior monks of Shaolin could not fly. But is that really the case? We can't see extragalactic galaxies and microbes and microscopic particles, so don't they exist? I think people can fly, but the final trajectory of people rushing out at a certain speed must be a downward curve. And to fly, the trajectory of movement is an upward curve. So, do you think it's possible? Mizukawa asked.

It depends on how far you fly. Short flights are achievable. Theoretically, as long as the person is fast enough and provides a small upward acceleration by himself.

Dueñas, it is not so easy to maintain an acceleration upwards. My method is relatively simple, which is to create an air stream that envelops itself and reduces the average density dramatically. Then, let the average density be lower than the air density. In this way, people can fly.

Six sons of wind come, your is even more difficult to do, almost impossible. How technically challenging it is to let the airflow wrap itself.

My method is simple, which is that people do spiral motion. Anyway, it's all flying, so why stick to the form. I think this is a more reliable method.

Margarita, it's not easy to draw a spiral, and still make a spiral motion?

The six winds come, but the spiral can keep the trajectory upward and is a curve. And isn't a tornado spiral?

You're all talking about it from a physical point of view, and I think if light work exists, what would it be like?

I don't have anything else to say. A question came to my mind: how can a bottle cap be poured when it is placed on the bottle? Through observation, I found that there is a pour-over limit for the caps. But why do limits exist? We know that the cap falls off because of gravity, but why is the cap partially suspended? Do you say that gravity acts on the geometric center of the cap? And this limit is caused by the geometric center. The geometric center must be at the mouth of the bottle so that the cap does not fall off.

Margarita, where do you say the geometric center of the cup, could it be in the empty space in the middle of the cup? If so, isn't gravity equal to hanging in the air? It's very cloudy, which is not in line with the laws of physics. I feel that the cup should have two geometric centers. One on the side and one on the bottom.

Place the milk carton vertically on the top of the bottle, so that it is all over the bottle. Otherwise, the milk carton will fall over. However, when 90% of the milk carton is placed on the top of the bottle, it still falls over. You say it has something to do with the geometric center, but isn't there a geometric center inside the bottle at this time? It follows that the geometric center does not speak of the situation in which the negative object is subjected to gravity. Just like a milk carton full of milk is placed vertically on the top of the bottle, the milk carton still needs to be all on the top of the bottle. However, shouldn't the geometric center at this time be determined by the milk inside? Of course, this is not to say that geometric-centrism is wrong, but it is not a universal law. For example, the cap does not fall because of its geometric center. In addition, the shape of the object will also affect its placement at the mouth of the bottle. Let's say you put a popsicle on the mouth of a bottle and keep pushing it towards the edge. As a result, you'll see that there is a limit here. Therefore, placing objects on the mouth of the bottle is not as simple as it seems. Mizukawa said.
