I'll give you the answer below

it's because the molecules that make up water and can make up scent are all air molecules but when you have water on it they weigh more. the molecules of a certain scent is a chemical composite that has very little weight. water has more weight than that of air. that is why it's harder to control things with a heavier molecule weight.
if anybody knows the answer and if I'm on the right path let me know so I know I'm not the stupid as I think I am or as others think I am
