A week ago I attended a talk given by Michael Connett, the son of long-time lawyer Paul Connett. Michael, like his father, lives in the US and has dedicated his life to fighting against the use of community water fluoridation. He's a lawyer, and specialises in civil lawsuits where there are claims of damage by toxic substances. He recently won a court case in the US where he argued that the EPA (Environmental Protection Agency) was not doing enough to address concerns about the risks of fluoride in drinking water.

In the lead-up to my appointment, the day before I had swallowed a teaspoon of green food-dye in the morning, and a teaspoon of yellow food dye in the evening.

In early January 2019, NZ Skeptics were alerted by an eagle-eyed supporter in Wellington to the almost unbelievable sight of a city-infrastructure employee apparently dowsing for water pipes on Willis Street! The employee was clearly wearing a 'Downer NZ' hi-vis jacket. Downer is an infrastructure company contracted by Wellington Water, the arm of the Wellington City Council which is responsible for maintaining the city's water system as a whole. Initially, we contacted the Wellington City Council, and were told they knew nothing about the dowsing. Our phone number was passed onto Downer, who contacted us, and seemed pleased to field enquiries which appeared to be other than complaints about noise. Downer eventually confirmed that the person really was an employee, and that they were indeed 'dowsing' for water pipes!

I've written about MMS - the "Miracle Mineral Supplement" - several times beforeA (here *and here*, for example). I guess it's a useful thing to hold up to show how something can clearly be woo - eg claims that it kills/cures practically everythingB under the sun - and yet people still buy the stuff. Buy it, and potentially do real harm using it. Because MMS is essentially bleach: 28% sodium chlorite in distilled water. Those using it typically 'activate' it by mixing it with lemon or orange juice, which gives the strong bleach, chlorine dioxide. And then they drink it, or - even worse - feed it to their children...

Around 300BCE there started a school of Greek philosophy called Skepticism. It continued for centuries, but was more like dogmatic doubt than the modern version. Bertrand Russell put their creed as "Nobody knows, and nobody can know". They may simply have a bad press. Carneades, one-time head of the skeptical academy, was accused of denying the possibility of all knowledge. In fact he seems to have denied the possibility of certain knowledge, a very different thing.

James Randi has demonstrated that a water diviner has a 94% chance of success in finding water for the simple reason that 94% of the land surface has fresh water immediately below its surface. The diviner is likely to fail miserably when he/she is asked to find a dry spot. The notion that water flows in rivers underground is only true for some exceptional places, usually associated with limestone deposits. Normally, water is trapped in microscopic pores and only moves a few centimetres to a few hundred meters per year. Similar misconceptions and statistics are seen in oil divining.

Our little Moon produces tides of 10 meters (32.8 feet) or so. Nibiru would produce a "Super-tide" on Earth, pulling the waters of our oceans up to where Noah's Ark was found on Mt. Ararat at the end of the "40 days and 40 nights" of rain. Of course, rain could not have produced such a flood as the Great Deluge, but Nibiru could have.
