 How does it work? It's actually really quite simple in that, you know, you immobilize a rhino. You can't put a kind of halter on it. You have to use some chemical immobilization. So you basically, and these are toys, I've put the rhino to make the rhino sleepy. You drill a hole in the horn or two, three holes in the horn, and you put these tiny little radioactive seeds into the horn. Then you seal it all up. No one can see where you've been. And then you revive the rhino.
