believed.
This would be an extraordinary finding though and there is a thing in science that says that
extraordinary claims require extraordinary evidence……which is why I had my hand in that
bag of seawater taped to my wrist.
If the water weighed the same after a few hours in contact with my skin (or even slightly
more due to sweating) I would have stopped there, but after three and a half hours it was ten
grams lighter. That would equate with a couple of litres if I was totally immersed in water all
day.
Interesting.
There’s another thing in science however, where a single experimental result doesn’t
count. But rather than repeat the same boring experiment over and over again I decided to
try something else. Full body immersion was the obvious next step.
Unfortunately, I had recently remodelled our bathroom, replacing the old bath with a nice
modern shower stall, so I asked some friends if I could borrow their bathroom for an afternoon.
Bob and Janet live in the next village to us and have two bathrooms. They are also quite
accustomed to my eccentricity so it was game on.
I turned up at their house with a towel, a bathroom scale, a couple of empty bottles, and
a paperback. They live in a house perched high on a hillside with a fabulous view over the
Ionian Sea to the mountains of Albania in the distance. From the bathroom window though,
all I could see was the shed and part of a tree. Never mind. I ran the bath and got in.
Don’t let anyone tell you that experimental science is exciting. It can be very boring indeed
and I did doze off a couple of times. Between naps I got out of the bath periodically to weigh
myself and have a pee in a bottle.
The results were interesting though. For the first couple of hours I lost weight but after
that I was gaining weight between weighings. Enough, in fact, to keep me fully hydrated,
based on recommended fluid intake.
I wasn’t thirsty either, not even finishing the cup of coffee that Janet made for me after-
wards – unusual for me.
This was getting quite exciting, but was it “extraordinary evidence”?
I couldn’t help thinking about those early hominids in the parched Miocene landscape. If
they could absorb water through their skin they would have been able to survive any drought,
especially if this worked with seawater.
Time for experiment No. 3.
Another important issue in science is confirmation bias. Confirmation bias is a well-
documented phenomenon that works like this: – say an experiment is set up so that the result
will be either blue or red and the researcher is pretty sure the answer is going to be red and
