A Cheap Part That Could Save Your Life in a Car Crisis

Although it's not very probable, it's still possible to become trapped in a vehicle with the windows closed and no means of opening the doors. In such situations, assistance might arrive in an unexpected way: a spark plug. It turns out that spark plugs are highly effective at breaking glass, including strong car windows.

The explanation for why a spark plug serves as an efficient tool for breaking a car window lies in its composition. Firstly, most spark plugs are made from aluminum oxide ceramic or porcelain. These are strong materials that, when hurled at a vehicle's window, concentrate force in a single area and deliver significant impact. Secondly, spark plugs are relatively heavy for their size, enabling them to exert greater pressure per square inch compared to other small objects. Take one out of the engine, open it to reach the insulation, then break the insulation apart. After that, move back and toss the pieces of insulation toward the car window, which should cause the glass to break.

No matter What kind of spark plugs does your vehicle use?, these inexpensive car components can be essential when attempting to assist someone (or yourself) from a locked vehicle. This method requires having a spark plug available, which may not always be the case. Fortunately, there are alternative techniques for breaking windows if that's necessary.

Different methods to exit a locked vehicle

If you find yourself trapped in a car that is fully locked with windows that can't be lowered, you should attempt to get the attention of someone nearby. You can use the horn, which is powered by the battery and may still function even if the car is turned off. Ideally, someone will arrive to either unlock the door from the outside, call for assistance, or try the spark plug escape method.

If this approach isn't working, you'll probably need to break a window that doesn't have spark plugs. If you happen to own a specific window escape tool — one ofessential emergency items to have in your car— it's time to make use of it. Spring-loaded tools are preferable, as hammer-style tools might have difficulty with tempered glass. If you're planning to purchase one, many vehicles will indicate the type of window glass on the lower corner of the window, typically either tempered or laminated.

If you don't have a tool, you might need to force your way out. Lie on your back with your feet against the window and pick a corner where the glass is most secure. Use all your strength to kick both feet against that corner until the window breaks. Ideally, you'll never find yourself stuck in a locked vehicle. However, if you do, it's wise to know several methods to escape quickly — and perhaps even keep an extra spark plug in the glove compartment.
