Part of Babson's entrepreneurial training is "fail fast, fail cheap". Students are taught to go forward iteratively with their ventures rather than rolling all their hopes into a single, giant, untested idea. And it seems that the Marshmallow Challenge is trying to accomplish exactly the same thing.
I'd be interested to see how graduating Babson seniors do in this challenge, especially given that graduating business students tend to do really poorly.
Let me know if you give this a try! I'd love to know how it goes!
