Becker Bottle - One in a Million
Produced by Flinn, the device is simple-a large 3-L bottle containing one million tiny colored spheres. When you challenge students to find the one black sphere (1 ppm) among all the other colored spheres in the bottle, they will have difficulty finding it, and the concept of a million starts to become real. Other colored spheres (10 ppm, 100 ppm, etc.) become increasingly easier to find in the million bottle.
