While flying skydivers in a Beech 18, we had an observer riding along for the ride down. As some on here know, the ride down is a 2 G maneuver in a steep bank turn to increase the rate of decent and save fuel and money.
The passenger started complaining about ear pain. I told her to hold her nose and blow, which was the quickest and easiest way to explain valsalva. I was immediately tapped on the shoulder by the rider and she complained that it was not working. Turning, I saw her most dedicated efforts at holding her nose and, lips pursed as in a whistle, blowing for all she was worth.
I laughed so hard I had difficulty getting out the words "with your mouth closed."
