Ridiculous Projects

I find it very peculiar to think that the methods, or projects, of the lower levels of society in Laputa are thought of since they seem like they would never work. This was when Gulliver was visiting this land with an individual named Munodi. In the book, there are projects that are listed as people blowing air through them to cure them. In my opinion, there seems to be no reasonable explanation of why that would work. This could be a representation in which these people are quite ignorant or have no reasonable sense in things. Also, another example of a project that seems ridiculous to me would be that they are trying to teach blind people on how to mix colors by using smells and touch.
