Mr Insane, my approach was to work on an average stick height and divide it into the speed of light per minute. Whatever, I don't think an Ambo would handle that kind of speed.
While we're being white and nerdy, a new element was added to the Periodic Table this year. It's called Ununpentium. Weird. Why not just call it Pentium?
I think you are right about the head. Would probably either disintegrate or melt before anyone ever got there!
I just read an article about Ununpentium. They said its name means one-one-five. Fitting since its atomic number is 115 and has 115 protons. Probably useless in itself as its half-life is .89 miliseconds.
