Introduction

Do you think it is easier to learn swimming in seawater or in lake water (in salty or sweet water)? Why?

What happens if you are in water and hold your breath? What happens if you then release your breath?

Why is it difficult to keep a ball completely immersed water?

Why balloons fly so high? Why a plastic balloon filled with helium raises in the sky while another balloon filled with air falls on the ground?

Why you should not fill a vessel completely with water if you want to put other things in it?

All these questions will be discussed and explained in the current tutorial, which deals with one of the most important topics in Hydrostatics i.e. Buoyancy.
