The Science of Fishing - Fact Number Two

Scientists have made a t v for fish, but if humans want to watch it, they have to wear some screen bazaars as its placed on the beach. Scientists developed a screen display that just includes the violet and the ultra violet spectrum. They'd reward fish if they pecked at certain ones to see if they could distinguish between the different u v wave lengths. And they could. But the thing is, of course, its giving uff lots of v radiation, and what we know about that is bad for us. So you got awaye factor 50 and sun glasses. L i don't think it's very good programms.
