Which boils faster, water that is initially cold, or water that is initially hot? How much does watching a pot really effect boiling times? If noone has a definitive answer, I’ll be forced to perform and experiment to find out once and for all.
Before you go to all that trouble, I suggest you search the SD and SDMB for previous times this question has been asked.
Quicker yet is this simple answer:
Hot water boils faster, watching it doesn’t do squat.
