The Equator

We visited the equator (in fact we visited 2 equators but only one had been measured via GPS!)

We witnessed water going straight down a plug hole when actually on the equator but either side ( a foot away) it went either clockwise or anti clockwise, depending on whether you we're north or south! Plus a couple other weird things, like loss of strength on the equator, difficulty walking in a straight line, due to gravitational pull. But also the ability to balance a raw egg on a nail:-)
