How Soap Changed the World in 7 minutes

In this episode of Discovery Insights, we explore the fascinating history of soap—from the earliest experiments with fats, oils, ash, and alkaline materials to medieval soapmaking, industrial factories, germ theory, modern hygiene, and the soap we use every day. Soap may seem like one of the simplest objects in our homes, but its history stretches back thousands of years.
