Today's OneWord: Airstream

If Claude followed the airstream all the way down the stairs, he would find the cellar where all of his uncle's wines were stored. But the bottles, when opened, would emit a foul-smelling, blatantly scarlet plume of gas, and the beverages would be effervescent, frothing, unwilling to be drunk without a scowl or wrinkled nose. So Claude never followed the airstream; he was too cautious of the odor.
