I think I saw this over at an old Kit-Up post. (Yes. It's here. I clicked out earlier and thought I lost it)
Very cool, he fabricated the vessel like a wing where the contact angle along with surface tension wick the fluid to the corner for sipping in weightlessness.
He also mentions that this is how rocket fuel tanks are designed so as to continue feeding fuel in weightlessness.
I love seeing problems which never occurred to me before and learning the ingenious solutions.
