When you have to write something really, really small, use a nano fountain pen. This chip is used to nudge atoms around into different configurations for quick nano-fabrication and creating nano-patterns. It has a “integrated microfluidic system for capillary feeding of molecular ink” and is based on the actual capillary action of the original fountain pen. I’m kind of weirded out by the thought of nanotechnology in general, so it’s a little hard to be funny. What about the children?
