Disappearing Penny

Experiment with refraction using the Disappearing Penny.

Ways to MESS Around:

Take the penny from below the glass and put it in the glass with water. Can you see the penny through the side of the glass when the penny is inside the glass in the water? Pour a small puddle of water on the tray and put the penny in the puddle. Put the glass with water on top of the wet penny. Is the penny still “invisible?”
