A simple design but some skill is needed. I used wire wool to act as the
internal fuel heater rather than a second internal cylinder (as per a you tube video)
Warning this is for Adults only. Scout Groups have banned these items as its
too easy to set your self on fire. ( I know my first attemp to make such a stove
resulted in me setting my shoes and pants legs on fire on a Duke of Edinburgh hike)
