    I have big fingers and I am looking for a way to attach smaller tips to my fingers.

    A hot dog?! That's a line I'm not going anywhere near!

    Seriously, though:

    Only works with your fingers. No gloves, no fingernails, no cardboard, no keys.

    It doesn't detect capacitance -- rather, the opposite. The screen works exactly like a touch lamp. Actually, it works like a few thousand touch lamps.

    There's a grid array of nanocapacitors that sit just below the screen, each one charged with enough electricity that they'll arc through the glass if there's a ground in contact with it. So you touch the glass, the capacitors directly under your finger release their charge into your finger (but the charge is so incredibly small that you could never ever feel it), and the iPhone knows where you're touching by which capacitors are requesting more electricity.

    So, that said, it only works with your fingers and other thin, conductive materials that your skin's in direct contact with. It will also work with a hot dog ;-)
