it is due to the surface tension of water. due to the inter molecular forces present in between the molecules of water, the surface of water behave as a stretched membrane. blade and paper clip do not exert enough force to pierce the surface of water. so they flot over the surface of water.
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.
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.
You can float a razor blade on water due to the 'Surface Tension' of the water. This is the tendancy of the water molecules to stay tightly together, which is why a water drop forms a 'hump' on a surface. Soap is a 'wetting agent', or surfactant. When you add soap to the liquid, the surface tension is drastically reduced, and the water molecules 'flow' around objects, like the razor blade. So, it sinks.
Yes, a paper boat can float on water as long as it is well-made and the paper is not too thin. The boat's ability to float depends on its design and the displacement of water.
A paper boat may sink in normal water because paper is not waterproof and easily absorbs water, causing it to become saturated and heavy. Once the paper becomes heavy, it loses its buoyancy and can no longer float on the water's surface.

Paper cups float because they are less dense than the water. Paper cups are made up of a light material, therefore making it float easily on the water's surface.
Well,I could say yes,but it also depends on what kind of paper u use,so technically,yes paper can float on water

yes
Yes, tissue paper is lightweight and will typically float in water. However, if the tissue paper becomes saturated with water, it may eventually sink.
As long as it can displace a volume of water equal to its mass (ie its density is less than that of the water) it will float. Most paper will have a density less than that of water (or can be so folded) so will float.
A dry paper bag will float until it becomes saturated
