Water Droplets Orbiting a Knitting Needle in Space [Video]

Sure, you have a general idea of how gravity works, how things orbit other things and the like, but it can be hard to really parse those kinds of things because they generally happen on such an enormous scale. That’s why experiments in micro-gravity can be so enlightening, and moreover, cool to watch. Check out this video of a water droplet orbiting a knitting needle, the first of many as part of a series being developed by NASA and the American Physical Society who aim to bring more cool videos from the International Space Station — and astronomical knowledge in general — down to Earth.

    The video is interesting but your post makes it seem that the orbiting motion of the droplet is due to gravitation between the needle and the droplet. You have not mentioned at all that the attraction is due to electromagnetic forces.
