Popular Science did a small article on the most worthless carbon fiber things. They had toilet seat (for you know, those really needed craps and you know your seat will beat your ass) bike pump (pumps really well, aluminium one was 200 dollars cheaper) Carbon Fiber umbrella, etc.
is the water repelling part CF also? I can't remember that article, but I do remember the CF toilet seat suprastore was selling them also LOL
