Doing these double blind tests correctly requires some time and consideration.
You need to do the comparisons a fairly large number of times to remove the possibility of chance.
It is best to get someone else to set up the test entirely for you, then you simply participate.
Then get that person to report on the results of the test.
It is really not the kind of thing you can do "when the office gets quiet".
It may surprise you that people in discussions on the Internet sometimes say they have performed a double blind test when they have not.
I recommend reading about this double blind test performed by Jason Victor Serinus on mains power cords.
Here you will see how one is conducted.
