Archimedes‘ principle
Archimedes‘ principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
This means that if an object is placed in a fluid (a gas or a liquid) and it is less dense than the fluid, it will float due to the buoyant force applied by the fluid. Therefore, if the object is denser than the fluid, it will not float.

Applications
Thanks to Archimedes' principle, boats can float in the water and hot air balloons can fly high up in the sky.
problems solved
Now, we can travel long distances in the water, as we do for shipping and cruising, as well as enjoy a beautiful view while enjoying a hot air balloon ride.
