Have you ever sat around and wondered, now what can I do with all of the old toothbrushes I have laying around? Well, neither have I, but apparently, someone has. They've even posted some ideas on the web (surprise, surprise).
Since the American Dental Association recommends you replace your toothbrush every 3-4 months (I think it's more often if you have a cat), you should have a few laying around your house. So instead of throwing them away, you can follow one of the ideas in this list. (Click here).
My favorite idea? "Make a little "bristlebot". Attach a toothbrush head to a vibrating pager motor and let it crawl around. Make a bunch and race them competitively. " I can see a group of engineers having a britlebot derby. Maybe they should try this on "The Office"? (whaddya think Neil?)
This goes under the category of "even geeks get to have fun once in a while".
