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!
What else can I help you with?
How can you explain surface tension?
Surface tension is a property of liquids that arises from the cohesive forces between the molecules at the surface. It is responsible for the "skin-like" effect that allows some insects to walk on water. Surface tension minimizes the surface area of liquids to maintain their integrity and is measured in units of force per unit length.
What is surface tension coefficient?
Surface tension coefficient, also known as surface tension, is the force acting on the surface of a liquid that causes it to behave like a stretched elastic membrane. It is a measure of the strength of the attractive forces between molecules at the surface of a liquid. The higher the surface tension, the more difficult it is to break the surface of the liquid.
What is surface tension in hydrocarbons?
Each liquid hydrocarbon has a different surface tension.
A consequence of the surface tension of water is what?
capillary action is a common consequence of surface tension.
How does the surface tension explain the pain a swimmer feels when he jumps off the diving board and does a belly buster?
Surface tension is the property of a liquid that allows it to resist an external force. When a swimmer jumps off a diving board and impacts the water's surface at a high speed, the strong surface tension causes the water to resist his body piercing through it, leading to a stinging sensation or pain known as a belly buster. Essentially, the swimmer's body collides with the water at such velocity that the water's surface tension is unable to accommodate the force, resulting in discomfort or injury.
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?
it's attraction force that attract the surface of fluid toward under
Can you explain the soap and pepper experiment and its significance in demonstrating surface tension?
The soap and pepper experiment demonstrates surface tension by showing how soap disrupts the surface tension of water. When pepper is sprinkled on water, it floats due to surface tension. Adding soap breaks the surface tension, causing the pepper to move away from the soap. This experiment helps illustrate how surface tension works and how it can be affected by different substances.
Explain how surface tension helps organisms?
By providing space and cracks in the Earth's crust.
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 keeps a water strider on the surface of water.?
One force I am positive about is surface tension- I can't explain too well because I am barely learning about this. I hope this answer helps you! =)
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.
How do you break the surface tension?
Adding surfactants the surface tension decrease.
Does water have the highest surface tension?
No, mercury has a higher surface tension.
