Make your own lunchbox icepacks from dollar store sponges soaked in water and put in ziplock bag. When they thaw, the sponge absorbs the water. I completely forgot about this handy trick! After lunch take squeeze the sponge and wash up hands and face!
HOW TO KEEP YOUR FOOD DRY IN A COOLER. Place ice and cans at the bottom of the cooler. Place cooling racks on top of the cans. Now you have a nice dry shelf to place food in. Great idea for traveling also!
