Read Turnabouts by Shel Silverstein.
Why does the author laugh at his own reflection?
So who is upside down?
Describe what you see in a mirror. How is it different from what you see reflection from a water surface?
Does your reflection look like you? Or do you look like your reflection? How do you know you and your reflection look the same?
If your reflection could think, what would he or she think about?
If you could talk to your reflection, what would you say to him/her or ask him/her?
What did the babies in the video do when they saw their own reflection?
Do you think they know they are looking at themselves?
How do you think they felt?
