Today on the podcast I interview science educator/TV personality/author/science demo-er, Steve Spangler. We talk about how very public science demos can compliment traditional classroom teaching, and how growing up in a family of professional magicians influenced Spangler's move into informal science education. I wanted you guys to have a chance to see some of Spangler's awesome videos before listening to the podcast, so I posted a few of them on Monday. To recap Spangler's resume: You might know Spangler from his appearances on The Ellen DeGeneres Show; his YouTube-produced show The Spangler Effect; any of his books, including Fire Bubbles and Exploding ToothpasteandNaked Eggs and Flying Potatoes; or one of his thousands of videos and TV appearances. (He is also often credited as the guy who "invented" the Diet Coke and Mento's eruption demo; while he insists this is not true, he may have been the first person to do it on TV.) Spangler is a professional science demonstrator: if you've ever seen a science demo show at an amusement park, a science museum or in your own school, this is a guy who's job it is to come up with those demonstrations and accurately explain what's happening.
