Glenn admits to hating science at school "I was subjected to endless droning sermons about photosynthesis and the periodic table of elements. I spent 98% of my time wishing to God I was somewhere else, anywhere else. And what did I learn? Not much".
Now he devotes his life to making science interesting, exciting, relevant and quirky. His books aimed at young people include Why is Snot Green?; How Loud Can you Burp?; and Stuff that Scares Your Pants Off.
