For example:- An object will float if it can displace the amount of water that would equal its weight. The amount of water a needle displaces is very little and thus is not greater than the weight of the needle. The ship, because it is not solid displaces enough water to equal it's weight, so it floats. the density of blade is less than the pin were drowned and saving blade does not.
