Tom Wujec: Build a tower, build a team. Tom Wujec is a Fellow at Autodesk, the makers of design software for engineers, filmmakers, designers. He presents an interesting research into the Marshmallow Challenge – a simple team-building exercise that involves dry spaghetti, one yard of tape and a marshmallow. Who can build the tallest tower with these ingredients in 18 minutes? And why does a surprising group always beat the average? What is the key to a successful product? Prototype often.
