First, I will drop a paper clip on the surface of water, and as you may guess it will sink. Second, I will put it on the surface very gently, and surprisingly this time it will stay on the surface! Then, I will add some soap foam to the surface area near the clip, and you will see what happens to the paper clip!
After these experiments, I will simply explain the concept of water surface tension.
