I saw this on the net and thought i would make one, it took around 10mins to make,
things needed
one shoe polish tin
one long strip of cardboard cut wide enough to be above tine around 2mm
candle
once you have cleaned out your tin, you need to swirl the cardboard around untill tin filled and then melt wax and pour in untill card is soaked, this takes the time, lighting up is not so easy and i tried witha bit of cotton wool and my strike but was no good so cheated with a lighter
once light it heated up the water in around 6mins, these can be used around 5 times, to put out just fit lid back on,
this did not work lol
it really gives off some heat
