Fitzroy storm glass

[Neil WyattModerator @neilwyatt]

This comment on Wikipedia suggests the exact composition may not be critical: " he compositions of the liquid in a storm glass varied but usually contained "camphor, nitrate of potassium and sal-ammoniac, dissolved by alcohol, with water and some air."

I suspect variation won't have much impact on it's spurious ability to forecast the weather; I suspect its appearance is a complex result of its recent 'thermal history'.

P.S. my Dad has one and considers it no more than a 'novelty'.

I believe in my first post I said I was making it as a "novelty".

I have calculated with my rusty maths that adding 33ml of meths or similar. to 100ml of 40% vodka should give me the correct ABV of 54.8%. A good excuse to buy a bottle of decent vodka anyway.

Beware the fake Vodka, apparently fairly common…….

Disagree comments about nasties additives to stop it being drunk. Many years ago I and a colleague finished overtime and went into small pub near work, in Brighton. Very small bar crowded with drinkers obscuring goings on. Two scruffy men sitting at next table with half consumed pint glasses of beer. One looked around to see if anyone looking what he was about to do and furtively pours meths from a blue can (Boots) in brown paper bag. When the glasses were topped up with meths, the mix went the colour of "Esso blue"!

Got it wrong, memory. Concoction went pink, like Shell's "Aladdin pink" paraffin.
