How to Make Glow in the Dark Flowers

(Video Link)

NurdRage offers up an especially nerdy Valentine's Day present: glow in the dark flowers. It's a simple process. Just drain the contents of a magic marker into a jar of water. Cut the stems off of some flowers and stick them in the jar. Let the flowers sit in the solution overnight. In the morning, after they have absorbed the fluorescent dye, they'll glow in the dark when exposed to ultraviolet light.
