Give your Christmas lights a creepy second life with ping-pong eyeballs.
1. Cut out a selection of eye images from magazines, newspapers, or websites.
2. With a sharp knife (adults only), cut a T-shaped slit in each ball, then fold back the corners, creating a hole that will fit one light.
3. Glue an eye image onto each ping-pong ball, holding down edges as the glue dries.
4. Slip each ping-pong ball over a lightbulb and hang.
