This enterprising fellow is very good at spinning a toothbrush on his finger, and he wants to share his talent with all of us! It looks remarkably simple to learn, and you'll surely find endless hours of enjoyment in this skill, should you choose to acquire it.
HOWTO spin a toothbrush on your finger
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
