What you do (Bounce, bounce, see): 1. An adult cuts a window near the top on one side of the carton and near the bottom on the other. 2. Tape one mirror at 45° behind each window, the two mirrors facing each other. 3. Look into the bottom window and adjust the mirrors until the view is clear. 4. Peep over a table or wall — never point it at the Sun.
