Erica takes us back to the time when prehistoric man first discovered that fire was not just something to fear, as was the case with animals, but something he could make use of, and later, something he could produce.

Discovering fire had a huge influence on the daily life of prehistoric man. Erica describes perhaps the earliest technique they used for making fire, and goes on to tell us about a famous mummy.

Erica shows us the various parts of so-called "tinder fungus" and then demonstrates how to prepare it for lighting a fire using a sharp flintstone.

We finally get to producing the fire itself, using tools found in nature. It's not easy at all, but when you finally succeed, it can be pretty exciting and satisfying.
