xkcd tests the 9V battery hack

It would have been self indulgent to call this post "xkcd is a lifehacker" but.. turns out that Randall Munroe, the creator of the excellent webcomic xkcd is, well, a lifehacker. :) He's blogged about the same 9V battery hack which we blogged about overnight, and put the hack through its paces.

There was some speculation on reddit that it was a hoax of some kind, so as a good sciencer (like a scientist, but we don’t get the lab coats) who really didn’t want to get started on the morning chores, I decided to try it myself with a new 9V I had sitting around.
