For making the tar, we used an oil barrel that was cut in two. The barrel was crammed with fatwood, and then turned upside town and dug partially into the ground to make sure no air comes in to the barrel. Underneath is a metal sheet and tube, that leads the tar out. The tar is extracted by lighting a fire outside and on top of the barrel, wich heats the fatwood up, and tar comes out. After 4-5 hours, we had about 4,2 litres of tar.
The self-sufficiency class has been in the woods collecting fatwood, which is now made into tar, which has been used for making shoe polish and ski wax. Look at the photos to see the process!
