Spark plugs are made from steel, and tend to be quite heavy. They’re also very hard, which means that the windows of your car are not designed to withstand the force of a spark plug being thrown at them.
In addition, because spark plugs are so heavy and hard, they tend to break windows even when they’re being flung gently into them.
Why do spark plug pieces break glass?
Spark plug pieces breaking glass is a common problem that can happen to any vehicle.
It’s caused by two main factors; the spark plug itself and the way the vehicle’s engine is designed.
The first factor is that spark plugs are made out of metal, which means they’ll eventually wear down over time. This becomes especially bad in extreme temperatures, when the metal can expand or contract more than usual.
When this happens, it can cause the spark plug to break apart and create small pieces that fly into your window glass and shatter it.
The second factor is how your vehicle’s engine is designed. If there’s enough torque (or force) applied to the engine at just the right moment, then those tiny pieces of metal will find themselves on a collision course with your window glass—and you’ll end up with a broken window!
Will throwing a piece of a spark plug at a car window break it?
When you throw a piece of a spark plug at a car window, it will not break the window.
The reason for this is that spark plugs are made of ceramic and metal. When you throw a spark plug at a car window, the ceramic will shatter, but the metal will not leave any marks on the glass.
In contrast, if you were to throw a piece of glass at a car window, then there would be an impact point and scratches on the glass where the glass hit it.
Can a spark plug really break a windshield?
This is a question that has been asked for many years, but the answer is simple: yes, it can.
A spark plug will break your windshield because it is made to produce sparks in order to ignite the fuel inside an internal combustion engine.
These sparks have enough force to break glass and even metal when they are traveling at high speeds. There are several ways that this can happen:
1) The vehicle may be moving at high speeds when the spark plug breaks through the glass and hits something else inside of the car. This can cause serious injury or death due to blunt force trauma from being hit by a piece of metal traveling at high speeds.
2) The vehicle may be moving at lower speeds when the spark plug breaks through the glass and hits something else inside of the car. This can cause minor injuries such as cuts and bruises due to blunt force trauma from being hit by a piece of metal traveling at low speeds.
