Whilst in Anglesey (Island off the North Wales coast for our friends across the pond), We were at an old brickworks having a picnic. These brickworks are only accessible by the sea or a short hike and someone mentioned we should make a fire as it was a bit breezy. Equipped as I was with shorts, T shirt and sunglasses there was no suitable wood for a firebow or plough (all gorsey brush). Nobody smoked and no one had a lighter or matches. So I got my kindling and fuel together andmade tinder by buffing a bit of kitchen roll. I stole one mates camera and some tinfoil that the butties were in.
Using my knife (i'm never without a knife) I cut a 1mm sliver of tinfoil about 4" long and coiled it around my tinder, touched the ends to the +and- of the battery and it lit the tinder like an electric fire....Lovely warm fire 3 mins or so later
