The presence of water is key, explains Bill Nye, aka The Science Guy.<br /><br />Directed / Produced by<br />Jonathan Fowler and Elizabeth Rodd<br /><br />Editor's note: Nye's latest effort called "Consider The Following" is a series of short videos in support of the ExploraVision Awards that are designed to get young people "excited about science so that we will have more scientists and especially engineers in the future so that we can—dare I say it—change the world." <br /><br />Be sure to check out http://facebook.com/ToshibaInnovation to see Bill Nye answering questions submitted by Facebook users for the "Consider the Following" series.
