The answer to No. 2 is to turn both hour glasses over at the same time. When the sand runs out of the seven minute timer, put the egg in. There will then be four minutes left on the 11 minute timer. When the sand runs down on the 11 minute timer turn it over. After the sand runs out the egg will be down (4 minutes remained when egg put in + 11 minutes from second time).
As foor the Loon food, yellow perch seems to be the favorite fish of the Loon.
