abstract:The Space Pen (also known as the Zero Gravity Pen), marketed by Fisher Space Pen Company, is a pen that uses pressurized ink cartridges and is claimed to write in zero gravity, underwater, over wet and greasy paper, at any angle, and in a very wide range of temperatures.
The pen's got enough space to hold 40 books or 175 songs, which can be played through an on-board speaker or via a headphone jack on top -- and you can also play books purchased for your Tag device.
