If you haven't seen it on an episode of CSI: Miami, rest assured that the MicroBlue is used by crime scene investigators to detect trace evidence. And for those of us who don't investigate crimes every day beyond who missed the toilet bowl, this gumshoe gadget may reveal stuff around the house, in your car, or at the office that you'd rather not see.

It's a forensic light source that in a darkened environment illuminates traces of bodily fluids such as blood, urine, saliva, and more as well as fingerprints dusted with fluorescent powder, which may be difficult to detect with the unaided eye.

You can even snap a picture of a stain by photographing through the amber shield (although that would make an odd entry in the family photo album).

The pen-sized illuminator runs on three AAAA batteries (included) and fits along with the amber shield in the included eyeglass case, so you can take it wherever you suspect foul play, or foul . . . fluids.
