We do one very similar to this one, as you said Wato3, the kids love it because it's gross!!!

macca,
I am obsessed with succulents!!!
I have a big garden in my back yard and two smaller ones out front! (not to mention all my little pups in pots)
I love what you've done there, I contemplated using chairs, it's great to see ones completed!
Well done you!

Hi all,
Lots of gardening and yard work.
Plenty of relaxing too!
Same here, PD day yesterday, have a few pracs ordered. Back into it!

Very true Lyn!!
Perhaps I should!
As soon as I open the door to the chem store I get hit with the smell
Then, as with you all, the flammable cupboard is another blast (of fumes that is)

We are trialling micro fibre cloths, so far they are working a treat!
They are pretty easy to clean, I just wash them in the prep rooms with hot water and suds, bit of a soak, bit of a rub and they come out reasonably clean!

HA! My exhaust fan has been broken for months!!
I have repeatedly put it on Sentral, brought it to the attention of the WHS committee, and then escalated it to the principal.....................
Waiting, waiting.................

Hi ocker,
are you still in the repairing business?
I have an induction coil that's not working......
I'm in Lake Macquarie.

Lyn wrote:$20 for 75g is pretty much on the money for the agar agar. ChemSupply has agar agar at $122 for 500g. So the price is reasonable from the health food store.

Yea, I thought so too!

Thanks Bigmack, I'll get some and try it considering the price!
I found some agar agar at a health food shop nearby, $20 for 75g.
Thanks all for your input!

Bigmack, sorry to be a pain, but do you know what product name it sells under?? I just rang my local woollies and they said they don't stock agar....
thanks!

Gee, thanks people! I didn't think to check woollies!!!! or health food shops!!

I did try the bludge option but agar is pretty expensive......so wasn't successful there.
I have made the teacher fully aware of the problem, I'm lucky my teachers are pretty relaxed, so she said if it doesn't work then she will just reschedule the prac when I have some

So, I have an order for Phenophthalein Agar for Thursday, only to realise I don't have any Agar......so I am experimenting with gelatin.
Has anyone tried this?
I'll let you know if:
1. it sets and
2.it works (or not).......................

Thanks Prima and Lyn!

Good morning all,

I am trying to source some Sulphur chunks without much luck! Has anyone purchased any recently? If so, where from???

Thanks Merilyn and Elizabeth!

Hi all, What bell does everyone use in their vacuum jars? :unsure: Last minute prac this morning, of course! Only had old bells, but we couldn't get it to hang in the jar. The bell sat on the base of the jar, it kind of worked but I need to buy a bell that will hang happily from the lid of the jar. ...

I wish I had access to a Woolies or Coles card too!!
We don't have our own petty cash anymore, but can get reimbursed from the office petty cash.
If my teachers were organised I could add what we need to the food tech order from Woolies..........but that's not going to happen any time soon!!

I'm DoE and I order from different suppliers. I buy from Serrata, Scientrific and Westlab mostly. Generally only use Office Max for stationery type things! Haven't been told anything different, so until I am I will continue doing what I've been doing. I also buy bicarb etc from woollies....much chea...
