I would like to give a big thanks to the people who helped me during my experiment. First of all, I would like to thank all the people who volunteered to taste the water. Without you guys, this experiment could not have been possible. Secondly, I would like to thank my parents who helped me and supported me during this project. Finally, I would also like to thank my teachers: Ms. Preston, Mr.Hensel and Ms.Izard who helped me during my project.
