Luminol and money

Money is dirty. These are some luminol traces on a banknote. Luminol is used to detect blood traces in forensic sciences and criminal investigations. In this case I think it is really blood. The money comes from a rural area in Africa where animals slaughtered on the market and the meat is sold directly from the butcher. This could explain the traces, at least I hope.

Lions in the Masai Mara

This is a group of lions that we saw in the Masai Mara National Park. A young male wanted to have some action while the others slept. It was funny to see that he looked like a high-spirited teenager and has probably just wondering whether he would prefer tourists eating or annoy the other lions.
