If you find yourself in an emergency situation where you need to break a car window, there are several ways to do it, and it’s important that you take the proper precautions.
For example, don’t use your hand or elbow to break the glass – they’re too hard and could potentially cause injury. Instead, try using a tool like a rock, screwdriver, or hammer to tap on the edge of the glass until it breaks into large pieces.

Can you break a window with a spark plug?
Yes, it is possible to break a car window with a spark plug, however, it takes multiple strikes for the window to break. A good location to strike at would be the corner of the window closest to the top of driver’s side door. The angle should be a little flatter so that it does not deflect off of the window.
What part of a spark plug can break a window?
A ceramic portion of a spark plug can break a window. This is due to the strength of the ceramic, which has been known to be able to crack glass with force.
The ceramic portion of the plug is able to break glass because it has a very high tensile strength, which in turn makes it have high compressive strength. With these two combined, the ceramic can break through glass very quickly and easily.
Can spark plugs break bulletproof glass?
What would happen if a spark plug struck a piece of bulletproof glass? This question is difficult to answer because there are varying types of bulletproof glass.
There are a variety of different types of bulletproof glass. The outer layer can either be made out of strong and durable glass, or polycarbonate which is more resistant against cracks caused by sharp objects like sparks plugs
Can spark plugs break any glass?
No, spark plugs can not break any glass. According to the US Federal Bureau of Investigation site, forensic experts have stated that spark plug fragments cannot penetrate tempered glass such as car windshields.
How do you break a house window with a spark plug?
The process of breaking a house window with an object like a spark plug begins with creating a crater or creating several cracks in the outside pane of the window, which doesn’t take much effort at all.
Once enough damage has been done, aim for either of those cracks/craters and hit it with the spark plug as hard as you can. This should send a large crack shooting up through the glass.
What kind of spark plugs break glass?
There are a number of different types, but one that seems to be the most successful at breaking both glass and other materials is the spark plug made by NGK, Denso, or Bosch.
Those spark plug types use a special ceramic shell around the central electrode which can break glass due to its somewhat lower resistance at very high voltages.
This phenomenon is sometimes called electric discharge machining (EDM) or dielectric breakdown.
Throwing a spark plug at a car window without noise
In the movies and televisions, people have been seen throwing a spark plug at a car window to silently break it. This breaks our idea of what should be possible in real life because if you’ve ever broken glass before, then you know that breaking glass usually makes noise.
In fact, the noise of breaking glass is often enough to draw more attention than the act itself. However, there are some kinds of glasses that make less noise when they break.
Variations in sound of broken glass
There are three different types of commonly used glass: tempered, safety, and laminated safety.
- Tempered glass is designed to break into tiny pieces of pebble-like pieces and it makes a lot of noise when it breaks, usually louder than the breaking glass’s natural tone. This is because tempered glass is designed to break spontaneously into many tiny pieces that don’t fly too far like they would if broken with a hammer or other such tool. Also, since these smaller pieces are easier to clean up, tempered glass is often found in kitchen cabinets and front doors.
- Safety glass has a very thin layer of plastic laid over the top of it, which makes it more difficult to break than normal glass, but if you hit safety glass with enough force, it will still break. Safety glasses aren’t designed to spontaneously break like tempered glass, therefore, they make less noise when broken because the boundary between the layers of plastic and glass isn’t as dramatic.
- Laminated safety glasses are made up of two pieces of safety glass that are stuck together with a thin layer of laminate in between them, which makes it very difficult to break through. They act similarly to safety glass when broken, but they make even less noise because the boundaries between the layers is more subtle.
In movies and television shows, a spark plug was used as a projectile for breaking a car window stealthily. In order for this to work, it would need to be thrown with enough force at the tempered glass without making any noise. However, since the tempered glass is designed to break spontaneously and makes a lot of noise when it does, throwing a spark plug with enough force would emit too much noise.
In summary, While there are some kinds of glass that make less noise than usual when broken, this phenomenon doesn’t apply to tempered glass found in car windows.
