"Scientist" implies a certain amount of knowledge, training, discipline, etc. I'm not implying that every scientist needs to have undergone academic training - there are other ways - but merely doing a scientific experiment is not enough to call yourself a scientist.
A scientist is one who "does science" with some knowledge, consistency and perseverance.
> In a more restricted sense, a scientist is an individual who uses the scientific method. [...] This article focuses on the more restricted use of the word.
