i have just come across something interesting that could be helpfull to someone,i have not tried this but aparrently holding two aa batteries end to end(pos to neg) then using fine steel wool to short out the other ends will cause steel wool to light on fire. we do not have any steel wool at home so i can not try this. with -22 and 30mph winds outside i cannot even get myself to go to store . would anyone let me know if they have tried this.
