At 0:25, I'm trying to decide who's more adorable — Alan Alda (aka Hawkeye from the TV show "M*A*S*H") or the kids he's working with. At 1:45, he nails why I never liked science classes. At 3:25, I'm laughing at the best science video/song I've ever seen. As if it can't get any better, by the time 7:21 rolls around, another one of my science heroes has delivered one of the best explanations of why science is important that I've heard in a long time. Why are you still reading this?! This video is action-packed, start to finish.
