Smoke over the sink…it uses the aircraft pressurization to drain better, just hold the drain open and the smoke will get sucked out (careful though, smoke detectors are in every lav ceiling)
It depends on how it’s been adjusted…some flow a shit ton of air, and some not very much. If you can hear air whooshing out the drain, you should be good as long as you blow into the sink 👍
It'll get wet
