Stick your head in it and breathe. You'll know.

Not only is that statement not true, as noted by others, it's also not at all relevant to what you're responding to.

  • Oh, so if you stick your head in a liquid and breathe you wouldn't know?

    • Sticking your head into non-liquid substances can have the same outcome. It therefore is not a suitable method for detecting wetness.

There exist lots of non-wetting liquids in which humans cannot breathe.

  • Your lungs have sensors that can detect being coated by a liquid which invokes coughing. In that sense, you can detect wetness.

    • They detect being coated, no matter liquid or not. (Source: Parents who smoke. And don't tell me the crap they are inhaling is a liquid.)
