It's just fun. There's nothing really to it, and no real point. But it captures the feel, at least as far as an outsider can, of the mind of a young child who is walking but not yet speaking in complete sentences.
It's a little bit humorous to see it set off as if she had considered the implications ahead of time and came to that decision, but it doesn't work as well as the followup book, 11 Experiments That Failed.
It's kind of formalizing the experimental method that children go through in their innate curiosity. It's funny. I don't know if children would like it as much as adults, but it might give them an introduction to the scientific method.
