The Astrobiology graduate conference (Abgradcon) happens every year, and I was there in 2009 at The University of Washington (UDub) in Seattle. (This year it's in Sweden)
On the last day we recorded me rapping to a class from a local high school; the Astrobiologists got involved too!
This is the video; it's just a precursor to.another bigger video that gives a different coverage of the talks and events at AbGradcon09. (Some of the footage from the other video has been included in this video; the other video contains over 100 BARS of scientific rhymes and should be ready mid to late July 2010 - [Actually completed in August 2012] - View it here- http://www.youtube.com/watch?v=n5OII7...)
