Why do broken spark plugs break glass?
When thrown with moderate speed at a side window, a sharp shard of the exceptionally hard aluminium oxide ceramic used in spark plugs focuses the impact energy into a small enough area without blunting to initiate cracking, releasing the internal energy and shattering the glass.
Can spark plugs break bullet proof glass?
A: Yes, a spark plug thrown at a car window will break it. So will a rock, a good-size ball bearing or a ball-peen hammer.
