What can cause a car window to shatter?
Considerable stress can build around chips, cracks, or other imperfections in the edges of a tempered glass window. Over time, environmental stressors like temperature, wind, and road vibrations can put those glass imperfections under even more stress, which triggers spontaneous breakage.What is the easiest window to break in a car?

How much force does it take to break a car window?
Answer provided byIt typically takes 20,000 to 24,000 pounds per square inch (psi) of force or pressure to break a car window. That translates to about 60 pounds of force. The smaller an object is, the less force it will require to break the glass.
How hard is it to break a car window?
Breaking your car's windows in an emergency might be tougher than you think, study says. AAA found that more and more cars are being equipped with laminated side windows that are almost impossible to break through.Can a window just shatter on its own?

If a window suddenly breaks without warning, it is probably because at some point during the installation, the edges were chipped and caused the glass to sit improperly within the frame.What causes glass to shatter by itself?
Spontaneous glass breakage is an extremely rare occurrence, however it is a possibility. There are a few reasons that glass would break without impact and the two main ones are nickel sulphide inclusions or thermal shock (also known and thermal stress).Why did my windshield cracked for no reason?
Temperature changesFluctuations in temperature, particularly if you use a defroster or even the car's heater, can cause the glass to expand and contract. Because the glass heats faster around the edges, these expansions and contractions occur at different rates, and this leads to cracking.
Can you break glass silently?
To break glass quietly, use a rag, blanket, or pillow to cover it before hitting it with a heavy object like a hammer. If you have duct tape, you can also use that to cover the glass. Another method is to use a steel center punch, pocket knife, or spark plug.Why is ceramic used in spark plugs?

Exploding glass is a phenomenon by which toughened glass (or tempered) may spontaneously break (or explode) without any apparent reason. The most common causes are: Internal defects within the glass such as nickel sulfide inclusions.At what temperature do windows break?
Glass is a poor thermal conductor and rapid changes in temperature (roughly 60°F and greater) may create stress fractures in the glass that may eventually crack. When heated, thin glass begins to crack and typically breaks at 302–392°F.Can car windows shatter from cold?
Very cold temperatures can cause a crack to in your auto glass to contract. The pressure from that contraction can lead to further damage. Contraction can also cause the glass to shatter, but that's an extreme case.Can you break a car window with a screwdriver?

Almost all modern car crushers use a hydraulic press to crush the cars. A large motor powers a pump that pushes hydraulic fluid to drive large cylinders. Using principles of force-multiplication, a hydraulic system can generate over 2,000 psi and impart more than 150 tons of crushing force onto a pile of scrap cars.Can a basketball crack a windshield?
At some point in your extended time driving on the road, your windshield may succumb to the elements of the road. Stones and rocks, basketball bounces on windshield while parked in the driveway or even drastic temperatures can lead to your windshield's cracked condition.
