2: Question 1 (1 point)
Gently lay the paper towel on the surface of the water in the bowl and the paper clip
on top of the paper towel, being extra careful not to let water come on top of the
paper clip. After a few minutes the paper towel should sink, but if it does not, gently
poke it down without disturbing the paper clip.

What did you notice? Did the paper clip float? Why or why not?
Yes, it floated. The water molecules at the surface of the water stick together
with cohesion and cause surface tension that prevented the paper clip from
sinking
