As we know that the ratio of the density to the volume is inverse relation.
As the volume of the object is lesser, than the density will be greater.So the condition of floating bodies depend upon the weight of the displaced liquid.If the object(needle) is denser,so it will not be able to displace more liquid.Therefore needle sinks in water.
A metal needle will sink in water, because it weighs more than the water does, and since it is not buoyant, it sinks.

Whether something sinks when it's placed on water is determined by the amount (weight) of water that it displaces. The needle, being small in size and relatively high in mass (relative to its size), displaces very little water when it is placed on the surface. The weight of the needle will be more than the weight of the water that it displaces and the needle will sink. The ship, though many times heavier than the needle, will displace alot more water than the needle. The ship will float if the weight of the displaced water is more than the weight of the ship.
A large log of wood floats on water because its density is less than that of water, allowing it to displace enough water to overcome gravity and float. In contrast, a steel needle sinks because its density is greater than that of water, causing it to displace less water than its own weight and sink.
When the needle is dropped parallel to the water's surface, it creates surface tension and stays afloat due to the weight distribution. However, when dropped perpendicularly, the needle displaces more water, causing the weight to overcome the surface tension, thus sinking.

The needle is solid, it's density higher than water's. The ship is hollow, its overall density lower than water's.

The 0.5g needle is denser than water, so it sinks. Ice is less dense than water due to its molecular structure and air trapped within, causing it to float. The buoyant force on the ice is greater than its weight, allowing it to stay afloat.
A ship made of steel floats because it has a hollow structure that displaces enough water to create buoyant force greater than its weight. A needle sinks because its density is greater than that of water, so it does not displace enough water to generate enough buoyant force to support its weight.
The water extracted by the wood log while floating is of equal weight of the wood or more. For this reason, the log of wood floats while a steel needle sinks.
Needle floats if u place it on the surface of the water even its density is heavier than water because there is a thin film on the water surface that is stretched towards the sides of the container because of the collision force of the molecules & this is called suface tension when u plae the needle vertically it tears the film therefore it sinks
Actually, its the other way around. A needle will float on water due to surface tension of the water. Thread will not because the fibers of the thread will break the bonds of the surface tension and allow the thread to sink. Also, the thread is not straight as is the needle.
