Build your own small-scale, high-altitude balloon out of styrofoam, masking tape, electrical kit and a 'consumer-grade' weather balloon. Two guys have reached an estimated 52000 feet using one they had built earlier. The UX-1 Balloon was launch on Saturday May 14, 2005, 10am Eastern time. Cool pics and video were taken throughout the mission. Next flight is in approximately 2 weeks with 100,000 feet the goal. http://sunsite.utk.edu/~mcoffey/ux-1/
