Wanted:

One manly-type cordless drill, with extra battery packs. I need to borrow it until the end of the week.
Anybody? Anybody?
Nah, didn't think so.

L recieved permission to build and bring and show off a working Van Degraaf generator to the academic fair on Thursday. But the rules say "nothing that requires electricity". We've taken that to mean "nothing that requires the schools electricity.
L's generator is powered by a cordless drill. Which we have. With 2 power packs. And the charger is broken. (dammit) Which makes the power packs useless. L used up the last of the power in the packs when he used the jigsaw attachment to build the base.

Today, I'm calling all my relatives and asking to borrow a cordless drill. I plan on borrowing as many as I can, so that L has back up power. It would really suck for him to put in all this work, and then be unable to show it off at the fair.

Tonight, L and I will build a back up generator out of 2 toy motors, a rubberband, a pair of batteries, a toilet paper tube, fine copper wire, and a pepsi can. The smaller contraption will generate enough static electricity to lift a few strands of silk thread. Not quite what we were going for; but if the larger generator fails, he'll still get a grade.

So wish him luck!
