I have been watching CSI: New York, CSI: Las Vegas, NCIS, and NCIS: Los Angeles for their entire duration ontv. Each week I seem to see more, and more new gadgets that I am not even sure actually exist. On NCIS they have a computer screen that they just move their hands over to manipulate data. On both CSI shows they have a table that they just place a computerized item onto, and it pulls the data for manipulation. I know that the ultraviolet lights for finding blood actually exist. I wonder if a blue acne light works the same.
Do these gadgets, and items actually exist, or are some of them fake for tv?
