The larger hourglass takes 11 minutes for all the sand to descend; the smaller takes 7 minutes. What do you do? ...Grandfather grows impatient... Corrine Mini-Contest 3 is Finished It was our third mini-contest. Now we have the first six correct answers and propose this contest's results and some details about the puzzle and its solution.

Our apology. We add his name to the winners list.
