Bicycle efficiency and power -- or, why bikes have gears. When you try to determine how fast a bike can go, what you do is you match the power available against the power required, at a given speed. This energy budget indicates whether you can go faster, or whether you can even hold your current speed.
Lint is the common name for visible accumulations of textile fibers and other materials, usually found on and around clothing. Certain materials used in the manufacture of clothing, such as cotton, linen, and wool, contain numerous, very short fibers bundled together.
I love the Scotch-Brite Lint Roller. I have a lint brush but I have to turn it the right way or it leaves more lint than what I started with. The Scotch-brite lint Roller takes all the lint away no matter which way I brush. I carry it in my purse with me. [This review was collected as part of a promotion.]
