Foluke Tuakli hopped on a bicycle and weaved around her classroom at the University of Maryland, College Park, acting out the problems that cyclists encounter on the road. "I'm turning, I'm turning," she shrieked as the bike wobbled.
The demonstration was part of a student pitch for a bicycle GPS app in a freshman entrepreneurship class in the honors college. Other student groups had their own pitches: a new type of sustainable drinking fountain where water is squirted directly into the mouth, a Third World slum development project, and a day care center that emphasizes healthful eating habits.
