They would take a piece of flat mica rock, which is highly reflective, and sit in a tall camel-thorn tree. They would then flicker, the sunlight off of the reflective surface of the rock at giraffes walking by hundreds of meters away. Upon seeing the flickering light, the giraffes would slowly approach the glimmering object, as it was something they had never seen before.
Out of an uncontrollable curiosity and desire to discover the origin of the light, the giraffes would approach within shooting range of the tree, upon which the bushmen would shoot them in their necks with poisoned arrows.
