The experiment which we are going to do is very simple.You can do this in any where and the experiment require the thing that is available in your home.You also can do this in your school science exhibition saying it is magic.But you know this is science.Before this try to place paper clip in water you will see that it will sinks.If you want to fun try below.
Material required.
- Paper Clip(Mandatory as we are going to float it)
- Water
- Tissue
- Compass(In math which you use) or anything
Procedure
- Pour the water in a bowl.
- Place the tissue in such a way that it floats.
- As the tissue floats place paper clip above it.
- You will see that paper clip and tissue will both floats,
- Using compass sink or remove the tissue in such a way that there is no reaction in paper clip.
- Notice the paper clip is floating.
- You can record it camera with too.(If you have video I will add it here just give me comments)
- You may watch video if you don’t understand it??
- If you have any other idea share it
Making a real science experiment
Sometimes you may fail that.To solve try this.
- Changing volume of water.
- Changing size of paper clips
- Changing type of tissue.
- Adding salt in water
Conclusion.
You have probably heard the word surface tension.According to science surface tension is
Surface tension is the the property of liquids that gives their surfaces a slightly elastic quality and enables them to form into separate drops.
It is caused by the interaction of molecules at or near the surface that tend to cohere and contract the surface into the smallest possible area.
It means there is thin layer in liquid.When you add that paper clip the thin layer will hold up.If it cannot hold paper clip will Float.
Glossary
Paper clip : The instrument which is used in document or paper to fasten many sheets of paper.
Layer : single thickness of something that lies over or under something or between other similar thicknesses
Tissue : a piece of soft absorbent paper that can be used as a handkerchief or a towel
