Fluorescence in the home

There are plenty of things around the house that fluoresce, often quite unexpected.

Food: Milk, bread, peanut butter, various oils, greens (lettuce, spinach, etc.)

Plants: Green leaves fluoresce red from the chlorophyll in the leaves, and some portions of some flowers also fluoresce.

If you purchased photography accessories you can try them out on these subjects. Your exposure settings in air will not be exactly the same as they will be underwater, but will be a good guideline as to where to start.
