Our ancestors invented a way of making light other than the flaming torch: they made lamps which burn animal fat that we call the tallow.
This lamp is sculpted from a soft sort of stone into the shape of a spoon. You put a bit of fat on top to act as the tallow and add some twigs. When you light the twigs, the heat makes the fat melt and the lamp functions like a candle, but giving more light and without giving off smoke.
A 45-minute activity for adults and children of 8 years and over to create your own lamp.
