Heh, I catch myself doing that all the time.
I remember spending a good amount of time figuring out the required current and potential difference across Misaka's fingers to propel a coin to the speed of a bullet, assuming she actually fires it the way railguns do.
We also played around with coilgun-style acceleration via magnetic fields using the length of the human fingers and a few ideal-scenario assumptions.
... So yeah, me and some friends got nerd-sniped by Railgun.
