About ten years ago, two scientists had a little extra time on board NASA's low gravity aircraft and came up with the idea of popping water balloons. Mechanical engineers Seth Lichter, of Northwestern University, and Mark Weislogel, of Portland State University, use the floating water balls to explain some basic principles of physics.
