We had a fantastic time this weekend at the US Science and Engineering Festival in Washington DC. Among the highlights of our visit, we sat insanely close to the stage for the Q&A with Mythbusters Jamie Hyneman and Adam Savage. We also had the pleasure to meet fellow diy Science authors Theo Gray (Mad Science, The Elements, Popular Science’s Gray Matter, etc.) and William Gurstelle (Backyard Ballistics, Whoosh Boom Splat, The Practical Pyromaniac, etc.).
