Automatic Toothbrush
I did a science fair project on this one... A tooth brush that had tooth paste in the handle which would dispense through a tube into the bristles. Of course to market such a thing it would either need to be disposable or refillable. I had a proto-type at the fair and everyone liked it. What do you guys think?
Reward: Just the satisfaction that I had a good idea. |
