Concerns about the results aside I found it wonderful that the people who carried out the experiment, while not producing a bulletproof scientific analysis, were very thorough and kept to the stated aim to have a fair scientific trial. Blinded randomization, repeated measurements, and further information about those tests would have been interesting to see, but the article manages to largely avoid jumping to unwarranted conclusions. They asked a fair question; performed systematic, documented experiments; and then produced compelling research to support their theory. Altogether it's a testament to using science to explore everyday questions.
