I didn't give you a downvote.

Reading the above, I realized it could be misunderstood.

I'm proposing to do the Eratosthenes observations from several latitudes at the same time.

So what do we assume the distance between the earth and sun is?  That's one of the chief problems with that experiment.

If you're willing to try, what you need to do is take a measurement of
- the angle the sun makes with "level"
- or, equivalently the angle a shadow makes



If you choose to take a shadow measurement, please verify that the item is vertical (with a plumb line or household leve) and report both its height and the shadow length.




 Yes, if your equipment isn't level then your calculations could be off.

Since water is always level it makes sense to use a water level to check your equipment and make sure it's level.

A water level is more accurate than even a laser.

Since water is always level.

Always.

Everywhere.  :)
