One fun fact about the Roman Empire is that they used urine as a cleaning agent. Urine, particularly from animals such as goats or humans, was collected and used as a cleaning agent due to its ammonia content, which acted as a natural disinfectant. Romans would use it to clean their clothes, whiten their teeth, and even to clean their homes. They had designated pots on street corners for people to urinate in, which were then collected and used for various cleaning purposes. This practice might seem unusual today, but it was quite common in ancient Rome.
