This paper clip experiment is about water tension. Did you know water has a skin. You can break it. When we did a floating and sinking experiment the things that were heavier than water sunk and the things that were lighter floated.
Mrs Blair told us that she could make a paper clip float. We didn't believe her so we all tried it any way.
Some people made the paper clip float by putting it in gently then Mrs Blair showed us how she could do it. Here is a video of the way she did it. You could try this too.
