In daily life, many secrets, tips, legends, and even "encyclopedic knowledge" of hearsay are customarily taken as "common sense." But which of these are real and which are taken for granted? Knowing it is not enough, we must know why. This is the purpose of setting up the “To Come True” column.
We hope that by using experiments that may seem superfluous, we should use as much of the "usuality" as possible to reveal the truth. Really, we are pleased to accept; false, resolutely rejected. Practice is the sole criterion for testing truth. We are convinced about this. Well, the truth is that we test the basic attitude of "common sense."
On the evening of July 21, Beijing experienced the largest torrential rain in 61 years of meteorological record. There were serious water accumulations in several low-lying sections of the capital. A man under the Guangqumen Bridge was trapped in the car and eventually died from the window. .
In today's increasingly popular private car, in the face of such circumstances, how to quickly break the window to escape it? High-heeled shoes, head restraints, fire extinguishers... Netizens all have tricks, so which tools are the most practical? Take a look at the experiment below.
Experiment time: July 14th, 14th: Experimental equipment: Audi car, Xiali car, safety hammer, small fire extinguisher, high heels (slim heel, thick heel), scissors, arm, foam board, car headrest (test vehicle With), Key, Nail Clipper Experimental Unit: Jilin Province Xin Jinmao Scrapped Automobile Recycling & Dismantling Co., Ltd. Experimental Expert: Jilin Province Xin Jinmao Waste Automobile Recycling and Dismantling Co., Ltd. Chief Engineer He Wenxue ■ Experiment No External Water Pressure Inside and Outside The same one, high heels experiment results: failure recommendation index: ☆☆☆☆☆
Many netizens said that when the windows cannot be opened, the high-heeled shoes worn by ladies can come in handy.
During the test, He Wenji sat in the cab and held the front of the heel shoes in two hands and forced it to the car window. Because of the small space in the car, the arm could not be opened and only the wrist could be used. After a dozen or so, only scratches were left on the glass. The same is true with the fine-heeled shoes.
Analysis: The interior space is limited, trapped persons can not use their full strength; shoes have a certain degree of flexibility, the heel is mostly made of rubber or hard plastic, will buffer part of the power.

Fourth, the car seat headrest experiment results: Xiali broke the window success Audi broken window failure Recommended index: ★ ★ ★ ★ ☆
In the numerous netizens' suggestions, many people mentioned using a headrest to break the window.
He Wenxue first unloaded the head restraint of Xiali car. Because he was familiar with the structure of the car, he only spent 3 seconds.
He Wenwen held the headrest with both hands and pointed the two steel reinforcements at the bottom towards the glass. Using only two shots, the Xiali window glass shattered once and for all. It took about 4 seconds, but the arm was also scratched by broken glass. Then the Audi car was tested. After five or six times, the entire window glass was even pushed away from the window frame. The glass was not damaged at all.
In accordance with the method of the netizens, he tried to insert steel bars into the window frame of the Xiali car and forced the glass to smash, but failed to break it up. In the experiment, when the Audi window was used, the reinforcement of the headrest was difficult to insert into the car frame.
Analysis: The same is the head restraint. Why is the result different? He Wenxue said: First, Audi's car window glass is filmed. Second, different types of cars have different glass thicknesses, so the results are different.
V. Small fire extinguisher experiment results: Successful recommendation index: ★★★★☆
Using a small fire extinguisher with a weight of about 2.5 kg, He Wenliang held the top of the fire extinguisher with both hands, and forced the bottom of the fire extinguisher to the middle of the window. It took about 2 seconds to smash the window glass of Xiali. The Audi window glass used two times, about 3 seconds.
Analysis: The fire extinguisher housing is all made of metal. No force is buffered when it is being glazed, and it has a certain weight.
Reminder: There is pressure inside the fire extinguisher, in case the quality does not pass, it may explode if hit hard. Moreover, female drivers may not have enough power.
Small fire extinguisher online purchase price of 30 yuan.
Six, safety hammer test results: successful recommendation index: ★ ★ ★ ★ ★
Yesterday, the reporter borrowed a safety hammer equipped on a large passenger car. The handle was made of plastic and was about 15 centimeters long. The hammerhead was about 6 centimeters long. He Wenxuan used a safety hammer and put a little pressure in the car. The glass of the Xiali car crashed. When testing the Audi car, it was also easy to break the window.
Analysis: The safety hammer has two pointed tips, which can concentrate strength, length, and use in the car. It is the most time-saving way to break the window.
Reminder: The correct way to smash the car window is to keep your arm open as far as possible, keep your upper body away from the glass, and cover your face with your other hand. Take a deep breath in front of the window. After the glass breaks, a large amount of water is poured in. Hold the seat belt with one hand and be ready to unlock. Hold the doorknob with the other hand and look for a floatable object to quickly move away from the car.
Security hammer online shopping prices more than ten to twenty dollars.
■Experiment 2 The external pressure of the simulated water outside the car was greatly simulated by the broken window effect when the water was on the outside of the window. The reporter and a worker stuck the foam plate outside the window and pushed it hard. He Wenyi was tested in the car and safety. Hammer and fire extinguisher broke the window successfully and all other test items failed.
Analysis: He Wenxue said that with the foam plate against the window glass, the glass is not evenly stressed, so the crushing may be easier. However, during the test, he did not dare to use his full strength for fear of hurting people outside the vehicle. Therefore, the test headrest was not successful.
(Note: This experiment is only for the test vehicle itself. The experimental conclusion is not used as a professional technical indicator. It is for reference only.)
■ Remind the front and rear windshields to be the most difficult to break. During the test, the glass on the door is more likely to be broken, while the front and rear windshields are difficult. He Wenxue said that due to safety concerns, most manufacturers of windscreens are laminated glass. When they hit, windshields often exhibit cracks, and the whole sheet falls off. The space inside the car is limited, and the windshield is tilted again. It is impossible to concentrate the force, so it is not easy to break.
From the driver's point of view, the glass that is most likely to break is the front left and right doors.
