The Instructables website might be a great place to look.

Here is a link to an article someone typed up about how they tested various fruits and leaves:

Subject: Household Products (or some such) That Detect UV Light

ISEN-ASTC-L is a service of the Association of Science-Technology Centers Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************

Many of us have heard of and/or use UV Beads<http://www.stevespanglerscience.com/product/color-changing-uv-beads> or UV Sensitive Paper<http://www.stevespanglerscience.com/product/sun-sensitive-paper> and the like. What I'm looking for is some sort of common household item (or combination of items) that can do the same - change or otherwise "detect" UV.   Perhaps there's some sort of recipe for such a thing that I'm unaware of (lemon juice and ...?), or some sort of very common plant that reacts to UV relatively quickly (and doesn't react when UV is blocked, or reacts more slowly to less intense UV).

If you know of something that fits the bill, I'd love to hear from you!!

Thanks for your time,

Dan
