Computer pens run on one 1.5 V AAA battery, have a remarkable ability to morph into a number of forms including a calculator, notepad, scheduler, keyboard with rhythm section and drums, journal, math and social studies teacher and Spanish dictionary. You tell it what to do by drawing or writing on a piece of special paper called “Fly Paper.” After you write on the paper, the pen does what it’s instructed.  A great, fun way for kids to learn something without being bored.
