Ok, here's a puzzle from real-life.  I don't know the answer.  
If you like to stir your rice before it's done, this is not for you:

1) Boil water in a regular sauce pan.

2) Throw in a cup of rice, any brand, and cover pan.

3) DO NOT stir rice before all water is absorbed! (Don't worry, only a 
few grains burn.)

When all the water has been absorbed, and you remove the cover, you 
should see holes in the rice created by steam coming up from the 
bottom of the pan.  The holes are arranged in a curious pattern: a set 
of concentric circles, perhaps 3 or 4, centered around the center of 
pan.  Why does this happen?
