🤔 in this amazing science experiment, we’ll show you how it’s possible using just water and a needle! “the property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules.” From what i understand, for the needle to float without sinking, some force has to balance its weight

Since no part of the needle is under the water, buoyant force can be ruled out.
True, a needle can float on water due to surface tension that counteracts its weight
Surface tension allows the needle to rest on the water's surface without breaking through, even though the needle is made of a denser material. If you get it right the needle should float on the surface of the water You should notice the the surface is pushed down by the needle If you push the needle through the surface it will sink
Also if you touch a little soap onto the surface it cause the needle to sink too. Surface tension is a fascinating property of liquid There is a thin layer of liquid molecules on its surface that can hold small objects like a needle The surface tension of water changes quickly when soap solution is added to water.
Water has a much stronger surface tension than alcohol, which is why a needle can float on water but not on alcohol
Water molecules are highly polar, which means they have a strong attraction to each other, creating a limited solidity on the surface known as surface tension. A needle can float on water due to surface tension The water molecules at the surface stick together, creating a film strong enough to support the needle's weight without it sinking. The surface tension that is a result of water's cohesive properties makes this possible
The cohesive forces create a skin on the surface of the water that can support the needle.) What property enables you to float a needle on water
