Boiling water with hot rocks.

Another method of boiling water in wood or bark vessels is to heat rocks in the fire and using a pair of simple tongs, transfer them into the vessel of water and the heat released from the rocks will boil the water.


This method can also be used to cook food.

Boiling water without a cooking pot

You may need to boil water for cooking or to purify it and to do this it is not necessary to have a metal cooking pot. If you have with you or can find a glass or plastic bottle, this can be utilised as a vessel to boil water.

Remove some embers from your fire and then fill the bottle with water and place in the embers (do not put a lid on the bottle!!!). The glass will not crack or the plastic melt because the water absorbs the heat from the fire. You must ensure that any flames do not go higher than the water level and that the bottle does not boil dry.

Here I am boiling water in a plastic bottle.

and here is a piece of video of me boiling water in a glass bottle.
