Wonder Boxes work like vacuum flasks. In these days when we are being warned of worldwide shortages of food and fuel, this wonder box and it's simplicity is designed to keep food at the temperature needed for cooking. Using very little fuel you only use about 15 minutes of energy to bring the food to the required temperature and then put it into the Wonder box. It makes it as though it were a thermos. On the flip side it will also keep ice-cream cold for about 4 hours.
