Understanding the Scientific Method

It is late at night and you can't sleep so you decide to turn on the tv and see what is on.  As you are switching the channels, you hear the announcer say, 'tired of tugging and lugging your hose. Its heavy and tangles as everyone knows.  Then you need the Xhose''.  Since you have never heard of it, you decide to watch the commercial.  For only $19.95, you can have the worlds first and only expanding hose.  How many times have we seen a commerial for a new product, electronic device or toy and thought, 'wow, that looks really cool, I wonder if it works like they claim'.  Now you are going to be the one to determine if it is really true.
