Because the popsicles in your freezer aren't made with DI water and the antifreeze in your radiator isn't mixed with DI water. (Seems like the obvious answer, but I've just been guessing all day....) -Chris Bill Kasprzak <[log in to unmask]> To: [log in to unmask] Sent by: TechNet cc: <[log in to unmask]> Subject: Re: [TN] Answer to Friday's question 03/18/2005 03:16 PM Please respond to TechNet E-Mail Forum; Please respond to bkasprzak I disagree. Why do Popsicle's stay frozen in my freezer while the anti freeze in my car is protects my car to 20 below F. Certainly my freezer doesn't go to 30 below F. Now I know why I'll get a bloody nose.

So, the original question was a tad bit on the devious side. However, if you did use enough DI water to completely dissolve each of those materials, they will begin to freeze in this order: First to begin freezing is the ethylene glycol (antifreeze), second will be the calcium chloride (Indiana's road salt), and last is the sucrose (sugar).

Its Friday and I am not less than 5 hours ahead of all you guys and now I will have to spend the entire week-end wondering about the true answer. My shot will be Calcium Chloride time because of the De-ionised water, then sucrose unless the water is hot, then the diluted anti-freeze. I haven't a clue as to why, just gut feeling. -- Regards Graham Naisbitt [log in to unmask] Golf quote of the week: If you watch a game, it's fun. If you play it, it's recreation.
