If you’ve ever had the secret urge to become a graffiti artist but have held back because permanently painting the sides of bridges and trucks isn’t your thing – rejoice. Here’s an electronic spray can that emits UV light onto a special 24″ X 24″ sheet of UV light sensitive material. Included with the kit is a aerosol-style can that runs on two AA batteries (not included). The graffiti can be sprayed onto the special light sensitive sheet (included) to create artwork that fades from view within an hour. Also included in the kit is a sheet of alphabet stencils for those of you needing help making your letters. The only question I have is – for $49 they can’t include two AA batteries?
