You must have access to a toilet with water that spins as it drains when the toilet is flushed.  Flush the toilet and make a note of whether the water spins clockwise or counterclockwise (when viewed from above).  Then either email me the result or write down the result on a piece of paper and turn it in by 5 pm next Tuesday (Nov. 15). Be sure to include your name and remind me you're in the T Th class.  No photographs please.

Many of the toilets on campus won't work.  The water doesn't spin, there is just a sudden whoosh as the water is forced down the drain.  If you can't find a suitable toilet then fill a sink with water and note the direction of spin as the water drains.

Here are some of the responses I have received in past semesters.
