Gravity is often given as an explanation for why things fall, as well as magically holding all water to a convex surface; however, an overview of buoyancy & density within a given medium will cover most, w/ magnetism cinching the bow. We see that heavier masses sink, while those lighter rise, such as a balloon compared to a brick. We see that a rock thrown in a lake will drop, unless the stone is made of pumice, where its pockets allow flotation. Then, electrostatics & interacting charges create the well-known ‘sticking’ force, & oppositely, levitation!
