Abusing freebiesA friend of mine recently attended a 'Champaign Lunch', where he was compelled drink as much fizzy stuff as he could between the first and last courses. In an ideal world we'd ask restaurant staff to tell us stories about fatties stuffing themselves at All You Can Eat places, but we recognise that our members don't all work in the catering trade, so for the rest of you - tell us something about abusing freebies. BTW: Bee puns = you fail.

Internal resistanceWouldn't the internal resistance of the batteries limit this effect somewhat? I'm not fully aware of it, but you do come up against the law of diminishing returns.

Yup.You're correct- the internal resistance is what will cause them to heat a lot. Practically speaking, I would say that you could maybe get 30V out of it, but with a bunch of them hooked in parallel you start getting a fair bit of current. Ever shorted out a car battery and seen the arc from it? That's because of the current. He might not be able to get quite as big an arc with this, but it might be impressive nonetheless...
Besides, this is just one of those pointless guy things to do.

Done this...Tried lighting a normal bulb with 25 odd 9V batteries. It works for a second, then stops because of the resistance. BTW, the batteries didn't catch fire or anything.
