My wife and I were recently backpacking on the beach. She brought a jiffy pop popcorn cooker. I suggested she cook it over the pocket rocket rather than the very hot campfire. She chose the campfire.
She heard my unspoken "I told you so" loud and clear as the jiffy pop burst into a flaming grease fire after a couple minutes in the camp fire. I turned away to cover my smile and delight as I suggested that she might be able to douse the jiffy pop blowtorch with sand.
Only a wire (former perimeter ring and handle) remained at the end of the cooking process. Would have loved some popcorn but the "I told you so" experience tasted even better.
