@ All:

Sorry I have not been here much.

I just saw this on metacafe: http://www.metacafe.com/watch/2368671/sugar_and_sulfuric_acid/

Sulfuric acid and suger produces h2o (steam) and a tower of pure carbon!!!!  This might be a cheap way for me to get larger carbon blocks for the earth battery component for JT circuit experiments in the spring.  I know very little about chemistry but this is cool.  Thought some of you might like to see it.

WOW . good Find . I'll Dump Sugar in those Bad Golf Cart Batteries Just Kidding .. Wonder if its Cheaper than carbon Welding Rods ? Hey you know that Copper will peal off and it makes a good solder connection . I got some the other day and they are killer .

@ Gadgetmall:

Thanks.  It looks to be kind of porous but maybe it could be compacted into a good solid rod shape?  Maybe a pvc tube and a broom handle ram?  It should be pretty cheap to make I think.  The only thing about the copper on the welding rods, to me, it adding another metal into the mix.  you may end up getting some electrolysis or deterioration at the point of contact of the dissimilar metals.  I don't know this to be a fact, I was just concerned about it.  Plus, those rods are NOT available in my area as I had looked for a long time.  If I had found some, I would have banded them together and used them.

@xee2
excellent,

500K and 10/40 turns. mmm that is nice and interesting

Have you tried a secondary? 1 or 2 turns might light it up very brightly... 

Very nice.

Thank you,
