I think what you all are referring to wrt boiling di water is the lack of "particles" in the water may cause it to "bump". I know when I took chemistry- pre-biochemisty- we would add something to the boiling vessel to prevent that. Of course, I can't recall what it is. :-) ===== Kate, http://www.cs.colorado.edu/~kolina/advantages-of-formula.html Mom to Ursula (9), Sage (7!!), Benno (3) "You can tell the quality of a person by how they treat people they don't need." ~ a wise dad http://groups.yahoo.com/group/PY-teenAP/ For older attached kids' parents. :-) *********************************************** To temporarily stop your subscription: set lactnet nomail To start it again: set lactnet mail (or digest) To unsubscribe: unsubscribe lactnet All commands go to [log in to unmask] The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(R) mailer for lightning fast mail delivery.
