Going on a picnic this July 4th? Pack a “refrigerator” inside of your cooler so that when the ice melts it won’t soak all of your food. Pack a large plastic box with a lid or container inside your cooler. Pack ice around it—now you have your “refrigerator”. You can place anything you want to stay cold but you don’t want to get soaked inside the box. We learned this trick from friends when camping. They had mini “refrigerators” for breakfast foods, sandwich makings, and snacks. It works like a charm!
