Aug 27, 2025 · Have you ever seen a needle float on water? 🤔 In this amazing science experiment, we’ll show you how it’s possible using just water and a needle! Learn the science behind surface tension …

Dec 26, 2018 · 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.

Sep 8, 2016 · 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 …

Feb 27, 2025 · 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.

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 …

Jul 12, 2025 · 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 …

May 15, 2025 · For this activity, you’ll need a shallow dish filled with water, a sewing needle, and a dish soap. Start by filling a bowl with water. Using tweezers, carefully place a sewing needle on the …

Sep 16, 2019 · Here's a neat experiment you can try at home. All you need is a glass of water, a sewing needle, and a small slip of paper. Try This! Place the sewing needle on the little slip of paper and …

Jul 22, 2007 · 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. …

In this science activity, children will experiment with making a needle float on water.
