The magic penny

Today in science we used refraction to help a penny reappear.  When we lowered ourselves, we could no longer see the penny at the bottom of a dish.  When we added water to the dish, the penny reappeared.  The light reflecting off the penny changed speed and direction when it moved from the water into the air and then bent towards our eye.
