Dancing Droplets Rock Out On Space Station HOUSTON -- Expedition
31 Flight Engineer Don Pettit of NASA has taught more than half
a million internet viewers how microgravity affects scientific
principles by using everyday objects on the International Space
Station. In the latest video, Pettit takes his demonstrations to
the next level by using sound to oscillate water placed on a
speaker and letting the droplets fly. The investigation is part
of "Science off the Sphere," a video series featuring
experiments of Pettit's own design intended to show scientific
possibilities on the frontier of space. NASA and the American
Physical Society, or APS, developed a partnership to share the
videos with students, educators and science enthusiasts across
the globe. In the short, downloadable videos, Pettit has used
knitting needles and water droplets to examine static
electricity, demonstrated capillary flow by creating a zero
gravity tea cup, used thin water films to experiment with fluid
motion, shared infrared imagery o
