Here is another magnetic toy that turns heads. The Hoverpen has a gorgeous design and spins in a hypnotic fashion. It has a pedestal with a magnetic field that keeps it balanced. No batteries are required either. You can simply give it a nudge to set it in motion.
The Hoverpen also has a fully magnetic cap. You can use it at work to take your mind off things or simply write/draw things. Like what you see? You can find this levitating pen on Kickstarter.
