Techniques for making fire. Artwork showing three prehistoric ways of making fire. All three use friction to create heat. When an ember is formed it is used to light dry tinder that is used to start a larger fire. To the left are two Australian aborigine fire sticks. The longer stick is rotated rapidly between the hands whilst it is pressed into a socket in the shorter flat stick. The other two are Native American methods. At upper right is an Iroquois fire pump drill which uses a flywheel to generate friction. At lower right is a Dacotah (Sioux) fire drill bow, consisting of a bearing block, drill, fireboard, and small stiff bow.
