Simple, fun, and outrageously cliched (for me at least, since Im in a dorm and all) project to decorate for Halloween using a blacklight.
Step 1: Parts
The black light I used is a 30 in. Phillips 20W bulb stuck in a plastic holder that used to hold the light for my fish tank.
Step 2: Paint it on
I ordered some green UV paint on e-bay. Ill probably have it sometime next week, and hopefully it will stand out more.
