This is driving me crazy! There was a show in the late 1990s that was a kids detective show. We used to watch it on Fridays in school and the kids on the show would try to solve a mystery. The only specific example from the show that I remember is they taught us how to transfer your fingerprint to a piece of paper using pencil lead and a piece of tape. What was it? I think it might have started with an "S"? Maybe Snoops... snoopers... ahh I can't remember
