How To: Make your own glow-in-the-dark wall art

Take a break from watching your lava lamp, and have some freaky fun with phosphorescence. Inspired by the Instructables project: http://www.instructables.com/id/UV-Fun/

You will need:
-a pencil
-laundry detergent with whitener/brightener
-a bucket, paintbrush, and water
-a damp sponge
-two 18" fluorescent black light tubes with matching fixtures
-surge protector
-a blank wall or other surface

Warning: Test the detergent first on an inconspicuous part of your wall. Let it dry, then use a damp sponge to make sure you can remove it.
