Later, they found out hitting two pieces of stone together could make a spark (火花). The spark could fire dry leaves. In this way they could make the fire again if it went out. Then people also learned to make a fire by rubbing (摩擦). They made a hole in a piece of wood and put a smaller stick into the hole. They turned the stick again and again. After a few minutes they got a fire.
