This is SCIENCE FRIDAY. I'm Ira Flatow. 21 years ago this week, way back in October of 1991 on the first-ever episode of SCIENCE FRIDAY, one of our show topics was the ozone hole, that bite out of the Earth's ozone layer caused by chemicals in our refrigerators, air conditioners, cans of hairspray. Our guest that day was the late Sherwood Rowland, who would go on to win the Nobel Prize for his work on the ozone hole.
