How many holes does a straw have?


After you ponder that one, decide whether a coffee cup has a hole.  If you think not, is a coffee-cup-shaped depression in the earth a hole?  For answers (and more questions), start at Neatorama.

  1. Math major: A coffee cup is a straw. (The hole is the handle!)

  2. A tube, such as a atraw, could be viewed as either a) having a hole at either end, or b) being itself an extended hole.

    1. ... or no holes, because if a straw or your garden hose has a hole in it, it won't conduct fluids.
