It seems to defy the laws of physics, but a paper clip made of steel can indeed float on the water surface. The high surface tension helps the paper clip – with much higher density – float on the water. The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.
In this regard, how do you float a paper clip?
GENTLY place a dry paper clip onto the tissue (try not to touch the water of the tissue) 6. Use the eraser end of the pencil to carefully poke the tissue (not the paper clip) until the tissue sinks. With some luck, the tissue will sink and leave the paper clip floating!

Besides, what happened when you drop a paper clip in a cup of water?
Water molecules hold on very tightly to one another. The attraction of molecules towards one another at the surface of the water creates a sort of ‘skin’ that allows the paper clip to float. This is called SURFACE TENSION.
Why do you think the paper clip sank to the bottom of the beaker when you added a drop of detergent to the beaker?
It sank to the bottom because the force of your finger broke the hydrogen bonds holding up the paper clip. What happened when you added a drop of dilute detergent to the beaker with the paper clip balanced on top. … Yes, what was holding it up is the hydrogen bonds in a water molecule forming surface tension.
Why does pepper move away from soap?
Soaps and cleaners are designed to break down the surface tension of water. … The water molecules, however, want to stick together and maintain that tension, so they move away from the soap, carrying the pepper with them!
Why if you lightly place a paper clip in water it floats but if you disturb the water it sinks?
Explain why if you lightly place a paper clip in water it floats, but if you disturb the water it sinks. A paper clip in water will float because of the water’s strong surface tension, and the surface area of the paper clip, but when the water is disturbed the paper clip will sink sue to the density of the water.
Why is it possible to float a pin on the surface of water?
The pin floats on the surface of water because of water’s surface tension. When a pin is delicately placed on the surface of still water, it creates a small depression on the water’s surface. If the pin is of unit length, then through out its length, the water’s surface experiences a force T.
Will a paper clip float in salt water?
Dissolve 2 Tbsp of salt in 2 cups of water. Make sure the paperclip sinks in SALT water. … The object should float in salt water and sink in fresh water. If it floats in fresh water, add more weight (paper clip).
