A previous poster suggested soaking cardboard in lighter fluid and then covering it with wax as a firestarter. We have reasonable success using cardboard egg cartons, wood chips/sawdust, and paraffin. In the USA, Girl Scouts can't use fuel or fire starter that has to be poured (safety rules). We melt the paraffin (in a double boiler), put the wood chips or sawdust into the egg carton cups, and then pour the paraffin over the wood, filling up the cup. Then we just rip off firestarter cubes as we need them, usually 3 or so for a biggish charcoal fire.
