i want to do a science fair project that involves blacklight because i think its cool, but i dont want to do anything in botony (the study of plants) because blacklight and plant growth is old. can anyone one give me some ideas for a science fair project involving blacklight.

Here's a starter list:
1. Wavelength absorption, what affects XYZ have.
2. luminescence (glowing affect), what affects it.
3. natural luminescence, geological types (rocks, soil), natural items (cotton, etc.)
4. Cryptography, codes involving black light.
5. Do neon paints look brighter under uv light or natural light?
6. Do animals see black light?
7. Light physics: what are the blacklight properties? frequency, amplitude, distance etc. How do you make it weaker, stronger?
8. How is blacklight similiar or different from ultra-violet?
9. What is a Wood's lamp? How is it used in science and medicine?
10. Are all UV rays the same?
11. Do optical illusions work the same under blacklight?

you might try to illustrate the differences of growth, between long wave and short wave ultraviolet lights. if you are restricted to this in a botany class. you might want to check and see if anyone has attempted to isolated this study, according to specific wavelengths, as compared to the wave lengths of sodium sun lamps.

if you can rig up the Photoelectric effect that would be very cool - you'd prob get some Kudos from Einstein fanatics.
Look it up on wikipedia if you dont knwo what it is.

Hi. Many ordinary materials will glow under black light. Maybe have a white light/black light comparison?
