Step 1: Required Parts
I chose a 12" Long Extension tube. The bottom fitting just happen to perfectly fit my flashlight.
3. Dremel Cutting Kit
4. Dremel (I don't own a Dremel so I just attached the blade to my drill)
5. Colored Gels
I used transparent folders at $.50 each.
7. Aluminum Foil
Step 2: Cutting the Trench
Remove and discard the unneeded plastic.
Coat the inside of the pipe in glue
Line the inside of the pipe in the Aluminum foil. I blocked the top end of the pipe to stop light spilling through.
Use the Velcro to secure the colored Gels.
Step 4: Paint With Light
You'll need a dark room. The Light Painter provides a ribbon appearance with bright a dim spots depending on how the light reflects off the foil.
