erm well, i got a pieace on tinfoil then at rolled up and compacted a pieace till it was very dense and about the same height as the little bobble on the positive side, and slightly more width just to make it easier to put it in. The tricky bit is putting it on the the little bobble and closing the battery patch, but with some trials errors you should be able to do it. Anything that conducts electricity would work well, copper wire would work better but there was none available to me, but that basically how u do it. Again like i said before just try out different shapes and sizes to find which one work the best. Good luck Ignatious
