This film has a tight rhythm and a tense plot, which makes it very enjoyable to watch. While appreciating the beauty of the ocean and the dangers faced by the protagonist in the deep sea, it also popularized some safety precautions and diving knowledge for ordinary people. I'm not a professional, I just saw it in the video, and then I post it, there may be mistakes, but for non-professionals like us, the specifics are definitely impossible to understand, as long as you know the general idea, in fact That's it.
1. Don't go to the bar to hook up after a breakup!
If you are broken-hearted, you can really find a little sister to go for a skewer or eat hot pot, or even buy a lot of snacks to watch Korean dramas at home, lie in bed for three days and three nights, etc., really don’t go to the bar to hook up randomly! At least I've always felt that there are no serious people in the bar! Not to mention any scumbags who have been cheated, even if you meet such a reliable man in the film, if everyone goes to find exciting games together, there will be absolutely no good results.
2. Do not touch the illegal amusement facilities!
Going out to play, those informal facilities, no matter how fun they are, it is best not to touch them. There will be accidents on the ropeway. Is this kind of personal workshop safe? Maybe you will say it, but it is really fun, and there is no need to queue, the key is that the probability of an accident is estimated to be one in ten million. But no matter how fun, no matter how safe, how can it be safer than a regular safety license facility? Look, didn't the two sisters in the film have an accident, and after the first accident, the second line TMD broke again!
3. Don't rush up quickly when in deep water!
Many people will say that if you fall on the bottom of the sea and quickly rush to the water, you will not be finished. So fast, you will definitely not be eaten by sharks! But you will really get decompression sickness! You think this decompression sickness doesn't sound so scary, isn't it just decompression sickness, you can get it, as long as you don't die. I went to check it on purpose, and I got decompression sickness and had to be sent to a decompression chamber within two hours, and this decompression chamber is not available everywhere. There is a high probability that it cannot be cured, and the internal organs of the whole body will fail and directly hang up. In other words, if you think of other ways on the bottom of the sea, you might be able to escape. If you rush directly to the surface, you will basically die. Of course, you can buffer every few meters, but sharks don't give you time to buffer! Including other sea creatures that are carnivores.
4. Replacing oxygen cylinders at the bottom of the sea will increase the chance of being anesthetized by nitrogen, so hallucinations may occur.
What a terrifying thing to have hallucinations, if every hallucination occurs, at least you can find a way to escape, but if you have hallucinations, maybe like the little sister in the film, thinking that you are saved, so you lie there and don't move. Even if you call for help, you don't escape. The oxygen is limited, so maybe she will die there. My sister is lucky, and those people just found her. What if they didn't find her? The deep sea area is so dark and the sight is so unclear, how difficult it is to find someone!
5.1. Sharks basically do not eat people!
There are actually more than 400 kinds of sharks, most of which do not actively attack people, and they do not eat meat, but there are also more than 30 kinds, which are very aggressive and will actively attack people or eat people, such as great white sharks , oceanic white tip sharks, etc., are often eaten by humans. Generally speaking, sharks like to eat fatty meat, especially sea lions, seals and other prey. Some divers wearing dark diving suits may be mistakenly eaten by sharks as seals. If a shark eats a human, it may feel that human flesh is too unpalatable, and let go of it. Many people complain about how the sharks in the film don't eat people. They are not fierce enough. In fact, sharks are not interested in people at all!
5.2. Sharks have a more sensitive sense of smell than dogs!
It is said that sharks are not cold to human blood, but they are very sensitive to the blood of fish. If they smell human blood, they will probably ignore you. They like injured fish and fish corpses. But it is not ruled out that some sharks that eat people also like human blood? Or some sharks are so hungry that their minds are cloudy, and they may also eat people. A shark's sense of smell is the most powerful organ, especially for the smell of blood. It is extremely sensitive, so whether or not a shark eats people, it is best not to bleed. Maybe it will be hungry and unwilling to eat? This film and many other similar films where sharks eat people when they smell human blood, etc., may also be to highlight the dramatic effect.
5.3. Be sure to hide under the shark!
It is generally believed that sharks cannot swim and can only attack quickly or upwards. It seems that they cannot take into account the range below it, so after encountering a shark, do not stand in front of it, but hide under it! Just like in the film, the sister lets her sister swim against the bottom of the sea.
5.4. The nose is the weakness of sharks!
The shark's sense of smell is the most sensitive, but its nose is its weak point. If it is bitten by a shark as in the illusion of my sister, then attack its nose, or like my sister, buckle its eyes, it should be will be relieved.
5.5. Sharks don't seem to be interested in the calm you.
Sharks don't seem to dare to rise up for calm people, but if you see sharks all flustered and your heart skips a beat, maybe the sharks think you like it, so they put you in the stomach and let you enjoy it. beautiful.
5.6. Can flares drive sharks away?
The two sisters in the hallucination in the film are using flares to repel sharks, but I can't find any information that flares can repel sharks. But it is said that sharks are afraid of orange and yellow. Many people say that the reason why marine life jackets are orange is because sharks are afraid of orange. The flares in the film seem to be orange or yellow, so it may be because of fear of color. But this scene exists in hallucination after all, and it may not be so.
6. Can the back fly be used as a jack?
In the film, the sister's legs are pressed by the cage, and in the hallucination, she inflates the back fly and uses it as a jack. Of course, in the water, the weight of the cage is actually much smaller than that on land, not to mention that it is used as a jack , at least it can be used as an airbag. I don't know much about diving, so I don't know if it's really as magical as in the film.
In fact, there are really many places in reality where people will be put in cages, put into sea water, and people will watch sharks, just like in the film, but it should be much safer than the small workshop in the film. , but after watching this film, I was daunted by this exciting viewing project.
Although there may be some bugs in the film, such as falling directly into the deep sea area from above, the eardrum may rupture, etc., but overall it is quite sincere, and it introduces us a lot of escape skills and diving knowledge in the film, which can be described as It is entertaining. And at least I think, the two sisters are not too much. They have online IQ all the time, and they have been trying their best to escape, which is very good.
