1 Use of safety hammers

  the life-saving hammer, in fact, utilizes its conical tip, because the contact area of the sharp point is very small, so when using the hammer to smash the glass, the contact points to the pressure of the glass (not pressure Oh, but the unit area of stress) is quite large, this with the principle of the Pushpin is a bit similar, the membrane is easily punctured, And the car glass is subjected to a large external force at that point, resulting in a slight cracking, for tempered glass, a little bit of cracking means that the entire glass interior stress distribution was destroyed, so that in a twinkling of countless spider web-like cracks, at this time as long as gently with a hammer to hit a few more can remove the glass fragments.

The middle part of the tempered glass is the most solid, and the corners and edges are the weakest. The best way is to hit the edge of the glass with a safety hammer and the corners, especially the middle of the top edge of the glass, once the glass has cracked, you can knock a few more. It is said that about 2 kilograms of pressure can crush the corners of tempered glass.

  If there is no safety hammer, the female high-heeled shoes is also a very good thing, the heel is swung up to make enough effort to hit it, the finer the heel is better!
