According to Archimede?s Principle when a stone is in water

Answer / adrianrain
Although the stone does not float in water it does become
more buoyant in water then it does in air. This will make it
easier to lift. If you have a large pool of mercury (one of
the most heaviest liquids) you could probably float a large
stone on it.
The same principle can be shown if you take a large balloon
and try to sink it in water. It floats in the air due to
buoyancy but is hard to sink because it is to light in the
water.
