The Gumball Challenge: Held at high school and university campuses nationwide, student teams receive a $27 loan from Gumball Capital and have a week to generate maximum revenue. At the week's end, money raised is collected and then loaned out by the Gumball Fund to promising entrepreneurs in third world countries. By participating in this entrepreneurial competition, students experience how their energy and creativity can lift like-minded people out of the chains of poverty.
