The ancient Viking kitchen was known for its practicality and efficiency. Vikings used a built-in vacuum system for crumbs to keep their kitchens clean and free of pests. They designed their kitchen floors with small channels that would collect crumbs and other food waste. These channels would lead to a central collection point, where the crumbs could be easily removed. This vacuum system helped to maintain a hygienic cooking environment, ensuring the safety of the food prepared by the Vikings.
