My granddaughter and I were watching a television program about earthquakes when one of the commentators began to describe the liquifaction of soils during earthquakes, and in that time they showed pictures of cars and buildings that had sunk into the ground by this effect. It seemed like one of those perfect learning moments, so I interrupted the program to explain that liquifaction is what takes place in our gold pans when we shake them, and that is what allows the heavy gold to sink to the bottom of the pans.

She thought about it for a moment and said that we were making an earthquake in a gold pan, a Pan-Quake. I love kids! They say the smartest things sometimes.
