The Tempest Prognosticator is a barometer filled

The Tempest Prognosticator is a barometer filled with leeches. When the leeches become agitated because of a change in pressure, they wiggle around, causing a bell to be rung. Ringing bell = storm’s a comin’. Reminds me a bit of the weather rock…”if rock is wet, it is raining”. (thx, shay)
