@Steve - Hmm... a "headless" matchstick. Will any lil ol' piece o' wood do, I wonder?
I have heard about the vinegar, though -- maybe I'll try that.
I never gave it too much thought to be honest Susan - I do remember that she'd snap off the head and crack the match again before putting it in the pan.
It might be one of those self-fulfilling things - she never had an egg crack and she always put a broken match in the water! Just a coincidence
However, I just found this:

whole match as the phosphorus in the head does something. Sadly it's too long since I did Chemistry 'A' Level to offer any suggestion myself
