Did you know paper clip can float on water when placed slowly, but sink while sink when doing it fast? Did you know why? It's all because of surface tension. You can perform it. Put the paper clip very slowly on the top of water, keeping it as much parallel to the meniscus. If you do it correctly, and slowly it'll float.

Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible. Water has highest surface tension among other liquids. This is why it floats because of suface tension acting on paper clip.
