Technical point...a bowl of water will 'vaporize' into the air without boiling.
At any altitude
There is H2O content in just about everything. Check anything to do with firewood
There will be comments of 'seasoning' and the water content. Ditto furniture.
Ditto building lumber. ETC, etc, etc on anything that will absorb
water (including adsorption)...they all have water content listed as
a percentage
Costco...that is what management has decided to do and my guess for marketing
purposes based on a tiny, tiny bit of real world truth.
Sister is s die-hard Costco tire person and only wants nitrogen because she
believes in their marketing...until she had a low PSI tire and wanted them to
air it up...normally she gets it done spot on, but that day they had a long line
of buyers with tires to be mounted. They told her to wait in line...she called
to say she was coming over to have me air it up...
