With greater pressure at shallow levels. This difference in pressure as a result of the net force is likely to push the object, up to the top. The size of the force is equal to the difference of pressure between the dots on the bottom of the bar to the point of flow. Which is equal to the weight of the fluid that is in the bar of the flow. For this reason, the density is greater than fluid will tend to sink into. If the object has a density less than fluid, or with the appropriate shapes (such as ships). The force will be able to make objects float.
