the ceramic in spark plugs goes right through auto glass
I’ve tried that and been entirely unsuccessful at it. Bounced right off with no damage whatsoever, even when hurled from very close as hard and as fast as I could.
It’s just too small and too light to actually break anything.
I’ve not personally attempted it, ahem but AFAIK it’s fairly foolproof —though my sources* also preferred to grind/scuff down the metal bits a little to help improve kinetic transference. Who knows. 😉
