Question 03/99

HALF-EMPTY BOTTLE

You are riding in a train and have just opened a bottle of beer. How much of the beer should you drink so that after putting your partially empty bottle on a table (which is shaking) it would be as stable as possible?

This question was suggested by Sergei Flach.
(3/99) This question appears in the physics problem book by H. Vogel. (We thank Dr. Fred Goesmann for bringing this to our attention.)
