For some real fun if you have a large fleet of gliders, go out one
morning and set all the altimeters to 29.92 (or the current setting)
and see how much variation there is in the altitude read outs. You may

Even more fun, we set QNH of 500 ft. When the student is not looking,
I'll dial in -500 ft. Most don't catch it - the first time.
