Salt, pepper, Android

Après-ski in a cottage in Austrian Alps sometimes offers opportunities for weird experiments that don't involve drinking beer.

The compass in my mobile phone didn't show north and this salt and pepper stand was the culprit - it happened to be magnetized along handle. In combination with the magnetometer and the compass application in the phone it turned out to be a pretty good demonstration of a Hall-effect absolute rotary position sensor.
