Question

How can some objects which generally sink be made to float? example

Answer 1

If the weight force down is larger than the upward push of the water on the object then the object will sink. ... Many objects that are hollow (and so generally contain air) float because the hollow sections increase the volume of the object (and so the upwards push) for very little increase in weight force down.
