Help me use my nails as an iPod touch stylus.

I've seen the Nano Nails product that is supposed to turn your fingernails into a capacative stylus. I like this idea, but they aren't out yet, and anyway I want to do my nails myself! What can I use that's lightweight to attach to my fingernail so that it conducts enough electricity to operate an iPod Touch? [more inside]
