Tooth Colorings Printer Friendly Version
Somewhat like plaque candy and the paint on (overnight) tooth whiteners; we add a temporary color that binds to the tooth enamel and instead of tooth paint or coloring only part of the tooth, we color the whole tooth and we only need to wait until it wears off. I think that with white teeth as a back ground for any specific color that it would be spectacular to have a brilliant color from anywhere on the spectrum bordering on neon colors. We could match or contrast toung colors. Very pretty and very novel!
Reward: Some in all colors!

Eraseable Solid Ink in a Pencil Printer Friendly Version
With solid ink in a pencil form you can write and then sharpen the pencil or leave it dull for everything from fine point to heavy lines or medium lines. You can still use the eraser if the ink is eraseable. Ink pens go dry but the pencil with solid ink, depending on how solid, might last longer and you could tell when you're almost out of ink and get a new one in time to complete your writing tasks on time. Most schools and colleges require you to use ink, but they didn't specify which kind, only which color. We could make the solid ink pencils in all colors and use them for artistic purposes and other uses besides writing.
Reward: Credit

Disappearing Food And Drink Dyes Printer Friendly Version
Just like the old magician's joke of having ink destroy a white shirt to have it later disappear and leave no mark. We could manufacture food and drink dyes that would degrade and disappear after time and/or exposure to air so that our clothing, hands, sofa, carpet (family pet) etc. doesn't ever get stained, which can be very expensive to have removed (except from the family pet) and destroy and leave permanent marks all over the house or car or anywhere actually. With all the color and no chance of stain ever again, we could reduce worry and eat in the living room in front of the TV again. Yeah!
We would know when food goes bad as well by the color!
Reward: To see the day we have green wine... oh yeah... those are wine (coolers)! Ha! My favorite!
