Cool Pen Printer Friendly Version
I definitely like the metalic paint that is used on special made motorcycles. Though it cost about $500 a galon.
A pen may cost only a few dollars, and on paper the ink would change colors in the light.
Kids would love it.
Teachers would hate it.
Reward: A few dozen pens.

The Only Book You'll Ever Need! Printer Friendly Version
A pocket sized book, resembling a novel - with some important advantages... Instead of paper pages, the pages would be made of a thin, flexible, transparent plastic. There would be approx. 300 pages - small enough to carry around in any situation. This book would be digital. Tiny disks or microchips would be downloaded into a slot on the inner back cover, and the pages would magically turn into the pages of whatever book you downloaded - a Biology textbook, or War and Peace - any book in the world. If the 300 pages are not enough, there would be a "Continue" button the very last page, and when pushed, the remainder of the book would be continued from the first page...and so on, until the end of the book. For students, instead of carrying around heavy texts back and forth from school, they would carry this special book, and a small container of microchips or small disks containing their "books".
Reward: Save the environment - no trees need to be cut for these books! Less back strain from carrying around heavy text. Less waisted space in libraries and home bookshelves - more space for other uses. Very convenient, and practical!
