If you use a UV light source as a demo you should be aware of safety concerns and safety rules for both the student and the teacher.

Teachers should know the answer to this BEFORE they incorporate black lights into their classroom activities. Ignorance could expose students and teachers to permanent eye damage. As teachers, we have a responsibility to practice the highest standards of safety.
