Well, you've got my attention. Could you describe the fascinating manner?

I've just located a paper I read almost thirty years ago which relates
to this topic: "Apples in a Spacecraft" by Hannes Alfvén, Science, v. 173,
pp 522-525 (1971). No liquids here, but neat stuff anyway, easily
understood  by the undergrad physics student.
