Science fair topic.

My science fair topic is simple. i am going to try to find out what type of water boils the fastest. In this experiment I will take different types of water and I will boil 2 cups of these waters on a regular stove. I will stand by the stove with a stop watch, and I will record the time while comparing them. when I have done this I will write down all the data I have collected. This will then lead me to the answer to the hypothesis. Perhaps this experiment will change the world. Until then I will do my best to finish this quest of knowledge.
