Right, now this may not be the right newsgroup for this one but i don't know what would be the right one. I have a roll of copperwire, the kind you could see on a relais or primary winding but reasonable strong. the roll is marker 015 diameter. Can i do something funny/useful... with this as it's just standing here, say it's about 2kg. Suppose it's not enough to make a strong dynamo but what about high voltage, pranks...
