In the absence of modern kitchens, some Native American tribes made use of heated stones to boil water. The procedure is both simple and effective.
Step 1: Collect stones
Collect stones, taking care to remove debris. The stones should be about the size of a tennis ball.
Avoid stones that are porous and likely to fracture or crack when heated.
Step 2: Build a fire
Build a fire and wait for the coals to get white-hot.
Step 3: Place the stones in the fire
Place the stones on the hot coals.
Step 4: Place some of the heated stones in the water
Remove some stones from the fire using tongs and place them in the container of water.
Tap the stones several times against each other to remove ashes before placing them in the water.
Step 5: Replace the stones as they cool
Replace the cooled stones in the water with fresh hot stones from the fire. Continue doing this until the water comes to a boil.
