I'm finishing up this week's blog tour with a stop on Steve Spangler's blog. Steve Spangler is the author of several experiment books for children. He's also made multiple TV appearances, and he turned the Diet Coke/Mentos geyser experiment into an internet phenomenon. His website has science experiments for almost any topic.
