Collect three sticks, live or dead, each one about 3-4 feet long. Carve a point on one end of each stick, so that the tripod legs can stick into the ground a little. Lash them together at the unsharpened end and stand up the tripod. Tie three pieces of triangular cloth into the tripod, so that each one sits flat (one above the other). In the smallest piece of cloth at the top of the tripod, pack in green grass leaves or place in a folded bundle of cloth. In the second layer, add crushed black charcoal from a fire (no ashes, you don’t want to make lye). In the bottom layer, add clean sand.
