  1. This is amazing! I wondered how capillary action would behave in space, searched Youtube for it and now I can actually *see* someone do such an experiment *in* *space*!

    I do wonder though what hinders the water from spreading out over time with nothing counteracting the adhesion other than stronger adhesion where the plates are closer. I also wonder why the water creeps "up" with up not even existing in 0g.

  2. Thank you Frank for all these great videos. I know they are kinda old by now but I have been learning so much from your videos and wanted to express my gratitude.
