I need a couple cold packs by friday so I can't order them from somewhere. I only need them to last for about 2 hours, will the cold packs they sell to put in first-aid kits work? I have a styrofoam container with a little over a cubic foot of space, the outside temp will be 95-100. Will a cold pack keep the temp inside the container around 75-80 for a couple hours?
