They do not break(shatter) laminated saftley glass like windshields, I think you mean tempered safety glass as used in doors. It has to do with hardness. Glass is actually "harder" than iron on the Mohs scale, and spark plug ceramic (technically called "aluminum oxide ceramic") is much harder than glass. Aluminium oxide ceramic actually rates a 9 on the Mohs scale; diamonds are 10, glass is 6.5, and iron is 4.5. That's the key to the whole thing, and why it's surprisingly hard to break a window with a hammer and surprisingly easy to break it with a small, light little shard of innocent white spark plug ceramic.

Other answers (not accurate, read comments below) include:
- A spark plug is heavy this would be no mystery but if you mean how does the ceramic from a sparkplug break safety glass than your question will be answered.
- The ceramic from a sparkplug attracts negative electrons (Negative Static) A cars side or rear window (Tempered Glass ie safety glass) has positive electrons (Positive Static) If one were to throw a peice of sparkplug ceramic at a car window the first part of the ceramic that touches the window creates a miner spark explosion which temporarly weakens the glass to an extreme point than the rest of the weight of the ceramic breaks the glass.
- You can shatter a car window with a piece of ceramic from a sparkplug about the size of your pinky finger nail.
- Last I checked, POSITIVE electrons are positrons, a component of antimatter...rather overkill to cause a nuclear event just to break a window. Rethink your physics.---Although the answer is not correct... a positive electron can also be considered a hole, or rather a lack of an electron... not necessarily your exotic anitimatter.
Um, you probably shouldn't have had glass around the open spark plug hole in the first place. this could make it hard for your spark plug to fit into place, or even send the spark to the cylinder. You will have to take apart the head and remove the glass depending on how big the shard, or piece is.
Any ceramic can be used to break windows, basically any hard substance formed into a small point will break a window as it is focusing all the impact force to a small area. Car windows are made with toughned glass that makes it considerably harder to break than normal household annealed glass. when you overcome the breaking strength of toughned glass it shatters and crumbles into small pieces that become less dangerous in an accident the exception to this is the glass used in car windscreens which is laminated safety glass this is two sheets laminated together a layer of vynl which will allow the glass to break but remain in place.
you get a spark plug socket or one of similar size to fit the spark plugs, then you just put it in the correct location and screw it in snuggly(not too tight cause you will break the ceramic casing), then connect all the spark plug wires
Remove the spark plug from the engine. Attach the wire to the spark plug. Let the spark plug come in contact with the engine block. Make sure the ignition is turned on. If you have a safety bar you will have to pull it into operating mode. Pull the starter rope you should see a spark.
Twist boot then pull, this will break the seal from the plug.
Did it break close to the boot (point closes to the plug)? Be more specific with your question.
Well the easiest way is to pull the engine. But that's quite a task for someone that doesnt know how to change a spark plug. Pull the wires off the spark plugs on the engine. Not the box where they all hook into. Use a ratchet and a spark plug socket of the correct size to GENTLY break loose the spark plug. Twist plug out with fingers in a counter-clockwise direction. Reverse these instructions for installation. Try not to break them off or you will be in big trouble.
You can try twisting them on the plug to break the seal. Sometimes it is impossible and you need to replace the wires.
If you mean that the wire came out of the boot, then pull the boot off of the spark plug and use a spark plug socket to remove the spark plug.
Spark plug wire not connected to spark plug? Spark plug wire connected to Wrong spark plug? Vacuum line disconnected? Bad spark plug or wire?
To change the spark plugs in a Chevy Celebrity: 1. Give the spark plug boot a twist to free it up from the spark plug, then pull on the boot to remove the spark plug wire from the spark plug. 2. Use a 5/8" spark plug socket with an extension and ratchet or breaker bar to loosen then remove the spark plug. 3. Set the gap on the new plug to .045" then screw it back into the spark plug hole in the head. Tighten the spark plug and replace the spark plug wire. I change the spark plugs one at a time to keep from getting the spark plug wires on the wrong spark plug.
