I got the idea for this light box here at No Time for Flashcards. Since we are focusing on stars this week, we made our opening in the shape of a star.
All it took was a leftover box (ours was from our Christmas cards) with an opening cut into it and some construction paper taped to the back. We positioned the flashlight behind it and made it glow.
There are lots of great applications for this. I thought it could be neat to use it with our Fisher Price Little People nativity set. The wise men/shepherds could be out in the field following this star to the manger.
