For the experience.

Education shouldn't just be about a career.

I'd hardly describe a dustman as a cushy job. Out in all weathers, need to be fit, and put up with dreadful smells etc. Very early starts, too.

It's not a job I'd choose to do regardless.

Since when has it been an offence to drink Meths or Isopropyl alcohol?

If a pack of cigarettes says, "Smoking Kills", why aren't you charged with carrying an offensive weapon(s)?

It might not be, but I'll bet it is if you sell it knowing (or suspecting) it's going to be drunk.

Did'nt say it was, just it pays more.

Nope, my mum used to be though. I Dabbled in home brewing a few years back.

Citric acid isn't used for sterilising but to balance flavours. Sometimes malic acid is used and sometime tannic. Sometimes a combination.

And anyway, you can get paraffin easily anyway

I thought it was to provide an environment that the yeast thrived in.

IIRC you used to mix citric acid and sodium metabisulphate to make a sterilising solution (SO2 being the result).

"Dave Liquorice" wrote in news: [e-mail]:

I have - and very impressed that on the very day that it was announced, wikipedia had an updated entry mentioning that it had been used in the Lonodon bombing.

- is it still used in any refrigerators? And would it be extractable?

Vitamin tablets make useful propellant IIRC.

I I drive less than a mile out of Fareham on the A32 I can find it ready prilled in 1 tonne bags left by the roadside for a farmer...

Hi all,

We had our windows (softwood) replaced about 12 years ago, with double glazed PVCU framed ones. Recently I had a security assessment by the local CRO (crime reduction officer), he said they were "not robust", no further explanation, so any ideas what he's talking about and how to improve them???

Niel.

You can use citric as an acidity adjuster in the wine itself (which is what you describe), however it also works in solution with Sodium Metabisufate as a sterilsing solution.

The sodium metabisulfate solution evolves a gas (sulphur dioxide) which sterilises on contact. The addition of citric acid helps speed up the reaction IIUC. Very effective, but try and avoid breathing the fumes!

Since the 1970s full strength ammonium nitrate fertiliser has not been available. A mixture of AN and diesel fuel was used by irish terrorists for bomb making after the supply of high explosive was diminished.

[Ian Stirling]

I vaguely recall there is a way to synthesise explosives from asprin, that is salicylic acid (sp?). Picric acid?

[Andy Dingley]

No, that requires a Class 2 HGV.

Which isn't exactly hard to get, to be honest. But it's apparently more valuable than an Oxbridge chem degree.

[Dave Plowman (News)]

Not according to the 'knights of the road' on the uk.rec.cars.**** groups.

They're always whinging about poor pay, conditions and status.

[Mary Fisher]

No, that's a culture medium.
