  Your physics prof was nuts. There is a very easy way to demonstrate
  this effect to a class. Take an old Miracle whip jar and fill it with
  water attach a wine bottle cork to the lid using tape and allow it to
  float up in the water on a piece of string so that it replicates the
  balloon in the car scenario. (candle wax also makes a good attach to
  the lid) Then slide this rascal around on a table. It'll convince you 
  of the correctness of your expectations. 

  I got asked this question on my hp interview, the interviewer was less
  certain of the answer than I was so the above demo served to convince 
  him some monthes later.

  Try it. It works well.
