I can't say that I have ever actually boiled them...BUT, I do use a version of the paper towel method (with amazing success because I have small, deft fingers), where I put them in a folded/moist towel, then put that in a plastic sandwich bag, then stuff the lot into my computer case. The excess heat from the electronics provides a steady heat that has always seemed to make them pop faster. (I'm impatient, so I regularly call them bad if it takes as much as a week or more).
(By the way, thanks for the rep Pasta)
