Just Guessing, I'll say that the Popsicle's will freeze first, then the road salt and last, the anti-freeze in the car. No reason, just being intuitive. We never did say what the quality of the DI water was, so I agree with KB that the DI water has something to do with it. I sense a connection to the threads concerning DI water. I don't think the final answer will give me a bloody nose as suggested by the originator.

The term "Road Salt" means sodium chloride in my neck of the woods, calcium chloride too expensive as a road salt. Which one? Just 20 ml of water? Please advise.

It's sure to make blood shoot out your nose. Which of these 3 solutions will freeze first, second, and third and WHY will they freeze in that order???? 1) 10 grams of Calcium Chloride (road salt) dissolved in 20 mL of DI water. 2) 10 grams of Sucrose (table sugar) dissolved in 20 mL of DI Water. 3) 10 grams of Ethylene Glycol (antifreeze) dissolved in 20 mL of DI water.

Ethylene Glycol will freeze first Sodium Chloride second Calcium Chloride third Having said that I think it's a trick question because of the DI water. I'm certainly not a chemist and only guessing.
