water level

[pawnhead]

Things are not as constant as they might seem
None of the above are correct
a) if the water is rotating
b) if a suspended weight is being accelerated
c) the triangle is not on a flat surface.

Or:
d) If you warp the space/time continuum, and open a vortex to another dimension.

I of course know that sometimes water is not always level, I've surfed mast high waves in Lancelin.

I have observed no less than six Foucault Pendulums in various science museums around the world, so I did know that suspended weights are not always plumb.

And yes, I have observed that with a few large home made squares that I have made from time to time we had to make sure they were flat otherwise they were not always square.

So why the hell did I make those silly statements? I can't understand it. I must be loosing my marbles. Thanks for the correction Bob, I'll try to lift my game.

Cheers

If you use the long clear tube method, dont pour a bit of red cordial into one end as an afterthoguht. It is heavier than the clean water at the other end. (
of course this is jsut theoretical, I wouldnt ever do that.
