Objects fall down because of gravity. Flat-Earthers deny gravity & wrongly claim they fall down because of density. We can disprove flat-Earthers’ claim by setting up two different weights of the same material (thus, the same density) against each other using a balance. We can see the objects’ densities are not why they fall down.
In this experiment, we set up a bucket containing 2 liters of water on one side and a bucket with 1 liter of water on the other side. This arrangement would cause the balance to tilt to the side with 2 liters of water.
The objects on both sides have the same material (water), the same surrounding atmosphere, and the same density. On the other hand, both have different mass and volume.
Flat-Earthers claim density is the reason why an object falls. However, as the experiment shows us, the balance is tilted to one side while holding two objects of the same density. There must be another reason why the balance is tilted.
