Glass balloons would be better for flying than lead zeppelins

Making a balloon out of glass might not seem like such a great idea on the surface – but Hank Rawlins, a graduate student in metallurgical engineering at UMR, thinks glass balloons might turn out to be the best way to put monitoring equipment in the upper atmosphere. It's an idea worth considering, and, for now, it's an idea that's worth at least $5,000.
