Last week, National Geographic Channel re-aired the show "How Hard Can It Be" hosted by Eric Gocke & Vin Marshall (frequent contributor to Popular Science). The show documented the challenges, trials, and, most importantly, successes of friends attacking serious engineering problems with only the tools and materials available to the average Joe.  Over the course of three episodes the HHCIB Team launched a rocket up 50,000ft, sent parts of an ROV to the bottom of the ocean, and flew a house with only helium balloons, setting a world record in the process.  These feats could not have been accomplished without help from experts including the 3D Systems Alibre team who provided 3D modeling software and know-how to engineer real-world success.  For more show videos and information please visit: and
