history: Have you ever thought about red foods? Do you know what makes them red? Actually, I don't know that. I know what makes the planet Mars red though, it's iron oxide. For food is much worse than that actually. The dye Red 40 is actually made from crushed red beetles. My daughter, who is vegetarian, found that out. I did not know that. Is vegetarianism when you don't eat any meat like chicken or steak? Yes, and I learn a lot with her, I have limited red foods and gelatin now. Got it, what about the red sky? I know that it results from Rayleigh scattering. They say red sky at night is a sailor's delight, but red sky in morning, sailors take warning.
