How can you test how much weight the surface tension of water can hold?
Small insects such can walk on water because their weight is not enough to penetrate the surface. A carefully placed small needle can be made to float on the surface of water even though it is several times as dense as water. If the surface is agitated to break up the surface tension, needle will quickly sink.
Why do paperclips float on water?
Paperclips sink in water because they have a higher density. Unlike wood, a paperclip will sink not float.
Why does low-surface-tension-liquids-clean-better than high-surface-tension-liquids?
Low surface tension means high wetting as it represents low contact angle. It is therefore very easy for a low surface tension water / liquid to wet the surface ( usually solid) and get rid of the dirty in a same way a surfactant does unlike a high surface tension liquid which can't wett the surface containing the dirty....

Why do iron filings do not sink when placed slowly on the surface of the water?
Iron filings are typically made up of very small particles with a low density, allowing them to stay afloat on the water's surface due to surface tension. The small size and shape of the filings prevent them from sinking immediately and enable them to be suspended on the water's surface before gradually sinking as the surface tension weakens.
Does a paperclip float in water?
Yes a paper clip is able to float in water. Take a bowl, fill it up to the top with water, take a paper towel and put it into the bowl, let it sit there for 3 seconds...then put the paper clip on it, and slowly remove the towel. This is able to work by Surface tension.Depending on the size, some paperclips can due to the high surface tension of water.
Can the surface of water be made stronger?
yes with baby powder

Why a tin lid floats in a bowl of water but when it is crushed into a ball it sinks?
The surface tension of the water stops it from breaking the surface so long as it does not cut through it. The irregular shape and weight of a metal ball made from the same thing cuts the surface tension and breaks the electronic bond that exists between the water molecules at the surface.
Why do paperclips float on water?
Paperclips sink in water because they have a higher density. Unlike wood, a paperclip will sink not float.
Some insects can stand on the surface of water because water?
has surface tension that allows them to distribute their weight evenly and essentially float on the surface. The surface tension of water is due to the hydrogen bonding between water molecules. This unique property of water allows certain insects like water striders to walk on water without sinking.

What is surface tenion?
surface tension is simply liquid (usually water) molecules that join together and creates an invisible "skin" around the top of a glass when you fill it to the top very slowly and it goes over the brim but doesn't spill. surface tension is made by cohesion.

What substance is made by the lungs to help reduce the surface tension of water in the alveolar?
Pulmonary surfactant...see link for more information.
What are bubbles made of?
Well, I know this because I played with bubbles when I was 6-9 so yea. Bubbles are made of soap, but with air inside of that bubble. Bubbles are things that come in contact with solid will disappear or pop.
Can copper coin float on water?
A coin can float on the water under a couple of circumstances. The most obvious is if it is made of a material lighter than water. And the second is if it is broad enough that it can be laid on the surface (carefully) and in such a way that the surface tension is not broken.
