I have been involved in a few discussions of 'nanobubbles'. It is has been interesting because by simply asking for evidence, people seem to hate me. This is almost as interesting as it is distressing. Mostly they keep saying that people are negative without trying it and it it so cheap what is the big deal. When you point out that that is what snake oil salesmen say, you get told you are making personal attacks. It is very strange.
