Black Light Basics
Source: Martha Stewart Living, October 2008
To determine if objects will glow in black light, take an inexpensive handheld black light with you when shopping at crafts and hardware stores. Papers and fabrics glow in varying degrees, so search for those that shine the brightest.
These instructions will create a stable base for freestanding black lights so that you won't have to mount them. Two 4-foot-tall panoramic black lights are sufficient to illuminate a 12-foot square room (position them in opposite corners).
1. Coat a small bucket and a 1-inch-by-4-foot wooden dowel with black paint. Let dry.
2.Stand dowel upright in center of bucket, and fill bucket with gravel.
3. Set black light vertically on top of gravel, with switch and cord at top. Secure black light and cord to dowel with zip ties.
