Display a wood frame, and slide the front & back doors. Now show a plastic plaque that fits inside the frame with the picture of a white rabbit. This rabbit plaque is put into the frame, and now for the magic! The kids yell, “Boo!” The WHITE rabbit changes Black with fright! The kids are screaming! When the kids yell “Oob!”, (that’s boo spelled backwards”, he changes back to black again. Finally, after several color changes, they realize you are turning the frame around. Take the plaque out and turn it around. Imagine their surprise when they discover a picture of the backside of a WHITE rabbit!
