yep, you want the surface of the cup to be water repellent, i.e. apolar such as a tiny bit fatty so that you'll have nice small drops of the apolar fluid and then apply a very fine spray of water. I think that the water droplets would like to collect into bigger drops and that gets easier when they weigh more and find themselves on a sloping or vertical surface. Good luck with this! Sounds like a nice project (both making the cup/mug and making nice photos)
