Go on. You don't know, do you? Why '''is''' snot green? I'll tell you. Snot is green because it contains a special bacteria-busting protein which itself contains a form of iron that reflects green light and absorbs all other colours. Wasabi, the Japanese sauce, contains the same protein. That's why it's green, too. Hold that thought. Dried snot - you know, the bogeys that you pick and stick on the wall to drive your mother mad - isn't green because once it leaves the body and the air begins to dry it out, the cells in the snot containing the proteins - phagocytes - die and the green colour disappears.
