To *demonstrate*, float a dressmaker's pin or a needle on water.
If you can do it safely, you can also float an old-fashioned razor blade.
Then just tap them and sink them.
That should get the conversation going....
... and you can even have fun dragging them around the container with a magnet, plus - if you magnetise the pin/needle - you've got a rudimantary compass.
p.s. the reason you get badly injured/ killed falling from altitude into water *is not* surface tension - pleeassse don't spread that myth!

How can you explain surface tension?
it's attraction force that attract the surface of fluid toward under
What is surface tension coefficient?
define coefficient of surface tension
What is surface tension in hydrocarbons?
Each liquid hydrocarbon has a different surface tension.
How does surface tension affect your environment?
Surface tension affects everyone's environment in many ways. Surface tension is the property of water that makes life to exist as we are accustomed. Surface tension also makes our body cells functional.
Does water have a relatively high or low surface tension?
MERCURY has a higher surface tension than water. This highest surface tension between liquids is 487 mN/m at 15 0C.
Explain why the surface of water in a container is not flat but curved?
Surface tension.
Which best explain the surface tension of water?
cohesion
Can you explain surface tension?

Explain how surface tension helps organisms?
By providing space and cracks in the Earth's crust.
What is a force that acts on particles at a liquids surface?
Surface tension. It always tends to acquire minimum surface area thats why water droplets form spherical shape.

Surface Tension is found in what?
Surface tension is found in Liquid
What is surface tension coefficient?
define coefficient of surface tension
Explain why a swing needle can float on the surface of water in a glass?
Due to surface tension, the upper surface of water acts like a stretched membrane which enables it to float a swing needle.
What liquid have the strongest surface tension?
Mercury is the liquid with the strongest surface tension.
Is the inward force among the molecules of a liquid?
The inward force among the molecules of a liquid is Surface Tension
What is the effect of sodium chloride on the surface tension of water?
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
