Translation:
| Condition of the Rock | The Weather |
| Rock is wet | Raining |
| Rock is dry | Not raining |
| Shadow on ground | Sunny |
| Top is white | Snowing |
| Can’t be seen | Fog |
| Stone is swinging | Windy |
| Stone is bouncing | Earthquake |
| Two stones | You drank too much (Don’t fly) |
| No stone | Someone nicked it |
The sign is an almost exact copy of this one, except that the final line is different. (In the Slovenian version, the final line is also written in a heavy dialect, which is impossible to translate but adds to the humor.)
(Thanks Barbara! And thanks Black Betty!)
