Razor blades and paper float in water because they are both less dense than water. They are able to displace an amount of water equal to their own weight before they are completely submerged, enabling them to float.
In case of a razor blade, the surface area of the blade increases as compared to a steel block of probably the same mass kept in water. Pressure is inversely proportional to area. Hence less pressure acts on the blade in downward direction resulting in floating of it on water surface. Bouyant force exerted on the body increases than weight acting downwards causing the floating.
This is a interesting phenomena, it is caused by the surface tension of the water.
One theory (and I believe it is correct) is that because the forces between the water molecules are only to one side at the surface of the water (i.e. downwards just below the water level).
Because the forces from the other water molecules is only downwards at the surface, the water molecules on the surface experiences double the downwards force (no/less upwards force) leading to this almost hardened surface on the water and any molecules (the razor in this case) cannot (without extra force) penetrate the surface of the liquid.
You can search for surface tension I am sure you will find this better explained.
Yes. The surface tension will hold it up if it is carefully placed in the water.
A clean stainless steel razor blade don't float on water.

I think it can float on water.
no since alunimum floats steel does not
The shape of the ship allows it to float. Imagine a ship that was just a big block of steel, If you put that steel block into water, it would sink because it is denser than water. Ships are built with a hollow shape. The amount of steel is the same, but the hollow shape decreases the boat's density. Water is denser than the hollow boat, so the boat floats. Shaping the block into a hollow form increases the volume occupied by the same mass, which results in a reduced overall density. The ship floats because it is less dense than water.
That is because the ship is not pure steel. There are also spaces with air in between. This reduces the average density. Now, if the ship gets a hole, and water fills the spaces instead of air, the ship will sink.

razor blade
caz it has less dens
No. It may be denser than the ocean, but nowhere near dense enough.
The most common nouns that may be used with 'a blade of' may be a 'blade of grass' or a 'blade of steel'. There are other terms for a blade, for example the blade of a knife, the blade of a razor, or the blade of a lawnmower, etc.However, the noun 'blade' can also be used in an abstract context, for example:He wields the blade of power while I wield the blade of labor.
Wipe it off
The finest steel wool you can find i think it rated like 000 Or a Very sharp razor blade!
It depends on how the substance is shaped. Take 40,000 tons of steel. If you shape it into an ingot, it will sink. Shape it into a ship and it will float.
hahahahahah RUBBER DUCKIES OF COURSE
The answer depends on the shape of the object. Ships, made from steel, which is denser than water, do float!
On glass, any hard substance can be removed with a very sharp razor blade. be very careful and never pull the blade towards you. Always push razor away. If it is not a hard substance, (must be dry) use 000 steel wool. it must be at least 000, anything less can scratch.
