Does Waddington Met Office still have the weather brick on the windowsill. I remember the joy it brought at an 0-my-god (Zulu) briefing to read the instructions:
1. Touch brick.. .2. If the brick's wet, it's raining!. .3. If the brick's moving, it's very windy!
..and so it went on. <img src="smile.gif" border="0">
