As long as the feather stays all by itself, it will never sink in water, because its density
is much less than the density of water. If you really need to sink it, then you must
tie it to something much more dense, like a rock or a fishing sinker.
No, a feather will typically float on the surface of water due to its low density.
An egg will sink in water but will float in salt water. An egg will sink faster in hot water than it will in cold water.
Objects float or sink in water based on their density. If an object is less dense than water, it will float. If it is denser, it will sink. This is because the buoyant force acting on the object upward counteracts the force of gravity pulling it down.
To make a bottle sink, you can simply fill it with a material denser than water, such as sand or rocks. When the bottle is submerged in water, the denser material inside causes it to sink. This is due to the principle of buoyancy, where an object will sink if it is denser than the fluid it is placed in.
A submarine can sink and float in water because it has ballast tanks that can be filled with water to make it sink and with air to make it float. By adjusting the amount of water and air in the ballast tanks, the submarine can control its buoyancy and stay submerged at a desired depth or rise back to the surface.

anything denser than the water will sink in it.

Pour the water out
Paper will sink once it has absorbed enough water to make it heavy.
When a feather is in the water, it gets wet and absorbs some water. When a feather is still on a duck, the oil secreted by the ducks skin is in the feather and prevents the ducks feathers from getting waterlogged. Otherwise the feathers on the duck would get heavy with water and make it impossible for the duck to stay on top.
Yes, it may make oil sink if at some temperature the density of water goes lesser than that of oil.

You can make a substance that is more dense than water sink by placing it in water and allowing gravity to pull it downward. The substance will displace the water and sink until it reaches a point where its weight is balanced by the buoyant force of the water acting against it.
