Answer 1

Not exactly. They don’t form “drops” because of surface tension, but they will get smaller because of evaporation and that other mechanic that gets their molecules absorbed into the surrounding air, unless they’re being fed by a water source, in which case they’ll get bigger until their weight exceeds the surface tension’s ability to hold them back, and that’s when you get a drip.
