It's funny how learning happens.  Sometimes the funniest things can become a teachable moment and sometimes the funniest things can bring back something taught months earlier.  Yesterday I was making Indy's breakfast and he was in the kitchen 
waiting impatiently watching.  I was making him an egg and turkey bacon wrap (his favorite breakfast) when the steam building under his egg became too much and a small hole opened up to release it.  Indy got CRAZY excited.  Crazy, I tell you.  He started telling me how it was just like what happens in the earth when a volcano explodes.  He went on to explain about magma chambers, epicenters, shifting plates, vents, conduits and all manner of other things.  We 
studied volcanoes in August of last year!  I could not believe how much he remembered.  I was so proud.
I would have taken a photo of what we termed the "Egg-cano" (it did look like a yellow volcano shooting steam) but Indy was hungry and impatient and I was afraid it might burn.  And after the great taco shell fire of 2009 (taco shells can catch fire if they fall on the element, did you know that?) I didn't want to chance it.
