If you only have $5 and two hours of your time, how are you going to make money with them?I also gave the same assignment to my students at Stanford.I divided them into 14 groups and gave each group an envelope containing $5 in "startup capital."They can plan for as long as they want before opening the envelope, but once the envelope is opened, they only have two hours to monetize the $5.The event starts Wednesday afternoon and ends Sunday evening.By Sunday night, each team had to send me a slideshow explaining what they were doing during that time, and they were going to present the details of the activity to the class the following Monday afternoon.
