In this episode of scienceTASTIC we do our best to stay on topic, sometimes to little avail. Mark covers hypersonic space tourism, Mike ratches it up a notch with even more hyper- hypersonic space flight, and Joe washes his hands clean of it all. A zig here, a zag there, and we continue on with smart dust, real-life tractor beams, and making it rain with lasers. It was a bit of a journey, but we got through it. Together.

What we didn't get to: waiting for Mt. Fuji to explode and watching supernovae in 3D.
