I'm trying to keep Popsicles frozen longer in a cooler for about 4 hours in the heat opening and closing multiple times. I'm using dry ice, but would it help to use regular ice in addition?
Can you get a second cooler, dedicated to the popsicles? I would pack some ice in ziplock bags to supplement the dry ice and keep the cooler closed until you need the popsicles.
In honor of Professr Blais (haha), freeze to order... with liquid nitrogen.
no that wont work for me
I would approach it in layers. Layer of ice- Layer of popsickles-Repeat...The less you have to rumage in there or move things around, the better. Also, if you have an outdoors store nearby(or have enough to time to order online)you can get one of those thin insulating survival "blankets" (they look a lot like pliable tin foil)cut it and layer that in between the ice-popsickle layers if you want to get really technical. That should retain up to 90% of the temperature on either side.

If these are the type of popsicles you make in those freezer molds, can you set the mold inside a larger plastic container, fill that container up with water and (carefully) set that in the freezer to form a large ice block around the popsicle molds. The heat would melt that ice first? I'm not this type of scientist, and I am not sure this is a practical idea, but it's simple.
All you need is dry ice. I used dry ice to keep ice cream frozen for 6 hours. I also used it for week long camping trips to keep meats frozen. Don't add regular ice since the water will cause your dry ice to melt faster.
i think you ned somthing cold and i need to know how to keep a popsicle frozen for 6 hours no ice, electricity or an outside colling method
Yes, the dry ice worked great! I put 2 boxes of popsicles
In a small cooler with a block of dry ice from Kroger and took them for the kids after their baseball game. About 4 hours later, I passed them out still frozen solid!
