Ice Cake

Before bed, fill a mixing bowl (any size) with water and put it in the freezer for the night. In the morning it should be completely frozen. Turn the bowl over and let the ice slide out into another bowl or deep pan.

Place the 'ice cake' in front of your child, as well as a spray bottle filled with hot water, a small bowl of salt and some food coloring (if you trust them with it).
Have them experiment with different methods of melting/decorating the ice cake. It's fun to watch the colors spread, and the cake slowly shrink






I was just as entertained by this as she was.
