The appendage hanging down from the roof of the mouth at the rear of the tongue is called the uvula.
yes it normal
Probable not...you should get that checked out...
A tongue with a barbell in it.
Technically, the answer is yes, but the structure of the question requires more explanation. The tongue is warm and moist and when exposed to normal air, there will be some evaporation and water will leave the tongue and be absorbed by the air. In that sense, exposing the tongue can be called licking and an increase of water content of the air near the tongue can be described as the air getting wet. A question with greater information content might be one that asks how much water is absorbed from the tongue when exposed briefly to air. The answer will be a very small amount, so small as to be difficult to measure and certainly too small to notice when you do it under normal circumstances.
If they are the same color as your tongue, YES. If they are white, NO.
