Compare different mouthwashes for their effectiveness.
Introduction:

Manufacturers of different brands of mouthwashes often claim that their brand is better, kills more bacteria, and prevents bad breath for a longer time. 

Different brands of mouthwashes also have different price ranges. Are you getting a better and more effective product when you buy a more expensive brand? 

Like any other consumer product, mouthwash can be tested for effectiveness in removing bacteria and killing bacteria.
 
 Project description:
In this project you will perform experiments to compare different mouthwashes for their ability to kill germs. The experiments in this project require some bacteria growth experience.
