Here is an easy way to make a light box for your child to experiment with:
Line a clear shoe box sized container with waxed paper and tuck a strand of Christmas lights inside. After you snap the top on, leave a small end of the strand and plug hanging out of the side of the box. Plug it in and have fun!

Glass Beads are a fun item to add to a light table/box.

This post at Teach Preschool also shows how to make a light box out of a strand of rope light and a scrapbook paper storage container.
You can use sand to create different designs and pieces of art on your light table/box like they did at Casa Maria’s Creative Learning Zone

My kids always flock to a light box when they see one, yet I've never even thought of making one for our playroom! I love this idea! Thanks for taking something that seemed out of reach to me and making it doable with things from around the house.

Love these ideas. My neighbor gave us a little tykes table with a lightbox in the desk top. The desk is kind of large for our playspace but I wasn't about to turn down a free light table!! Can't wait to try these ideas out.

I just discovered the light box concept and was bummed to see how much they cost. Thanks for pulling together these ideas I have all these items just laying around at home anyway.
