Various objects of different densities are weighed outside of water and then weighed as they are being submerged. The buoyant force is measured and compared to the weight of the displaced water. In another experiment, two beakers with equal amounts of water are balanced on scales. The balance is immediately upset as an object begins to be immersed in one of the beakers. As the object is fully submerged (but not touching the bottom of the beaker), the balance is then restored by adding water to the other beaker, equal in volume to that displaced in the first beaker.
