Is this five?

Anna spent a full twenty minutes today shining a green Tinkerbell flashlight through a glass of water.

First it was a tall glass that had a pattern on it and then she insisted on a short, unadorned juice glass. She walked around the house, turning off lights and holding the glass up to different surfaces. She observed how the reflections looked against the wallpaper, the cabinets and various pieces of furniture. She looked at the patterns in the bathroom mirror.

Finally she returned to the kitchen to ask me, "Is this science?"

So far, five is kind of awesome.
