One of the most common proofs that the Earth is not flat, is that ships disappear from the bottom up over the horizon. But Flat-Earthers claim that it is not possible to see far enough because of moisture (or whatever) in the atmosphere and it is therefore not a proof of a globe Earth.
In this video I'm showing two experiments I did - one to determine how far a ship at sea is visible and another to see the effect of a change in height on a ship on the horizon.
Conclusion: The Earth is a globe!
