A needle can float on water due to surface tension. The surface tension of water is strong enough to support the needle and prevent it from sinking, as long as the needle is carefully placed on the water and doesn't break the surface tension.
When a needle is placed on the surface of water, the surface tension of the water causes it to be attracted to the needle, creating a depression in the water surface underneath the needle. This results in a downward force acting on the needle, causing it to sink into the water.
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 needle will sink in water because it is denser than water. The buoyancy force acting on the needle is not enough to counteract its weight, causing it to sink.
A needle can float on water due to surface tension. When the needle is carefully placed on the surface of the water, its weight is not enough to break the surface tension created by the water molecules, causing it to float.
The needle with grease floats on water because the grease creates a waterproof barrier around the needle. When placed on water, the surface tension of the water is able to support the needle and grease due to the decreased contact between the needle and water. This phenomenon is known as the "floating needle trick."
Because there is no gravity to pull you down. It is the same when your inside water.

No they dont they flaot around even when they sleep.
hot water has a lower density because since it is hot, all the particles repel from each other. therefore, cold water has a greater density that hot water which results in the floating effect

it can flaot in the sky like no other!
If you have floated a needle on the surface of the water in a glass then adding a little detergent will cause the needle to sink. This is because the presence of the detergent changes the surface tension of the water so that it can no longer support the needle.
Yes, a needle can float on water if it is carefully placed on the surface due to surface tension. However, if the needle is pushed down into the water, it will sink due to its density being greater than that of water.
I assume you mean "When your hot water needle does NOT work." Thermostat.
