Imagine you are looking inside my cup. You see some ice, a straw, and three rather out-of-place semi-circled rods permanently stucked along the sides of the cup.
Make a guess:
- What are those out-of-place semi-circled rods for?
- What functions do you think they serve?
- You do not see them in your regular cups don't you? Are they redundant features?
- If you wash a few cups how do you dry them?
- Is it possible to stack-em up and yet allow the cups to dry?
