Luminol for the layman

So the subject of luminol is fun.

But what would the average person need luminol for you ask?

1 - Checking for traces of dead hookers under the bed of a sleasy motel room, or just to see if they washed the linens

2 - Loading up in a Wagner Paint Gun, spraying all over your friends at a party to see what they do

3 - Spray on the dog to see what he does

I searched on yahoo and found that you can buy some on ebay here -> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=26420&item=3866463714&rd=1&ssPageName=WDVW
