in csi, when the investigators find the stain, they use a wet swab (which is wet by distilled water) to collect some sample, and then add 1-2 drops of some liquid to the swab. if it becomes pink or light purple, they would say it is positive for blood.
what the liquid is it? why this color if there is blood?

The pink stuff is phenolphthalein (fee-no-THAY-leen) and the spray stuff that glows is called Luminol.

The things they use on CSI are fake and inaccurate. The time slots the put on these shows and the process of doing this is all out of order and incorrect. If you want to really know. Become a detective or a doctor or something. I realize its just a show, but I feel all the same. TV is not all it seems.

Heidi is right about the phenolphthalein.
But I think a more pressing question is why the investigators are always using their little flashlights to examine the scene, when it would be way easier to just turn on the lights.
