Josh: This week it is all about lighting up your homework, notes and doodles. Now, you can literally spark your creativity with the stroke of a pen. Check it out.
Researchers at the University of Illinois have developed a new ballpoint pen that conducts electricity through drawing. The pen uses a silver ink that conducts, or transports, electricity on paper, wood and even plastic. The lines produced by the pen are perfect for transmitting electricity to or from resisters, transmitters or LED lights. All you need is a small battery, like this 9-volt, to power up your doodles and give them light or sound.
Another cool thing about these pens? They were made from regular ballpoint pens with the tips filled with the silver ink.
