A middle-aged uncle smashed the window into the water to save the drowning man. How can he find the point if he wants to break the window?
If you want to break the window, the best way is to use a special tool, namely the window breaker. As long as you hit a point a few times, the glass will naturally break. Generally, there are such window breakers at the window edge of long-distance buses or buses. Its principle is also very simple, that is, the fixed place is severely compressed, which will cause the whole plane to be compressed and eventually break.
If there is no window-breaking artifact, it is necessary to choose hard and sharp objects to break the window, such as a straight knife and a tactical pen, which can easily break the car glass. The specific operation method is also relatively simple, that is, aim the "tip" at the fixed position of the window and smash it several times more, so that the window can be easily broken. Don't patronize with brute force, aim at the fixed stress point of the window. When breaking the car glass to save people, try to choose the side window instead of the front windshield of the car, because there is a special coating on the front windshield to prevent the window from breaking, and it is very difficult to completely break it. Even if it is broken, this protective layer will prevent people from climbing out. Without this protective layer, the side window is relatively easier to escape. When choosing the "fixed stress point of the window", try to choose the corner of the window, because the corner position of the window is easy to break, but the stress at the corner needs a certain precision, so it is relatively difficult.
In short, if you want to smash the window to save people, you should first choose a sharp tool, and then apply force at a force point, and try to choose the corner of the side window and the window, which is easier to save people.
