Question 2 (1 point) Now take the paper clip, dry it very carefully, and then lay it on top of the water
again, this time, poking the water as you do it.
What did you notice? Did the paper clip float? Why or why not?
No, it did not float. Poking the surface of the water broke the bonds that make
water molecules stick together and that cause surface tension.
No, it did not float. Adhesion between the paper clip and the container made the
paper clip stick to the bottom.

Yes, it floated; adhesion and cohesion work together to keep the paper clip
above the surface of the water.
Yes, it floated. Surface tension can resist the light external force from poking at
the water.
