And for the non DET people with the IEU
The IEU are negotiating %5 raise but will not do anything till Public service get there's because they know if they grant more thae state govt then they will lose funding

2 Add 100ml of water and mush

I can't keep blue Litmus paper in cupboard, so I store in beaker set into larger beaker with small amount of Ammonia solution and Gladwrap over the top

Can't see the use for it, except we use fracionating columns for refluxing.

All my receipes just say dissolve in water, 0.5M=94.5g/litre

Sounds like nasty stuff you're using!
What's wrong with metho?

Hey Coxy!
Please elaborate, What's so great about them,
i.e. better design or just better quality control

When I did this prac I put small piece of metal either side of a strip of filter paper with a plastic peg, then lowered filter paper strip into electrolyte solution.
Measure with digital multimeter ( High Impedence) does not drag voltage down to drive meter.

I don't like snails, because they are intermediate hosts to so many diseases.
As soon as I see one I remove and kill Jah Ha Ha

G'Day Labbies
I have a Geiger counter made by Science Resources and Development Unit NSW Dept. of Education that I believe is now defunct.
What I need is a new Gieger Muller tube that plugs into the counter.
Does anyone know where I can source this or where I can go for further information?

The reason your magnet disintergrated is they are very brittle, even if allowed just to slam together, they will chip. If dropped they will break, I always store mine with a chunk of polystyrene between

The problem is, if I have a day off, I'm not replaced and the teachers just help themselves and leave twice the mess than when I return have to work hard just to get back to square one.
So what happens if we go on strike?
