Ann, I'd accidentally buy a $20 one from Big W with petty cash, until they get you a proper one. :thumbup: I accidentally bought a microwave once. Oh and a "thermal heat transfer unit" that as well as performing Latent Heat experiments, also, completely coincidentally, makes coffee. :w00t:

Well all the best, and happy quilting!

The Title of the Prac., is "Where are those germs"

And the answer is: Not in my lab!

We also use ours for Biology/HPE. Get the little treasures to run around, and then take their temperatures in their motuhs with clinical thermometers, and off their foreheads with the non-contact thermometer and show them how sweating cools you down, since their sweaty little foreheads will be coole...

Yep, as long as its 5 water to 1 H2O2.

What's worse than no-one caring? Having a new HOD make a fuss about getting them up to date, and her Labbie saying unhelpful (and apparently uncooperative) things like: I have lessons to prepare/washing up to do/supplies to purchase/public buildings to burn down. :crazy: You know - normal days at wo...

You are not wrong. NO human pathogens. No no no.

What's the purpose of the prac anyway? Looking at "germs" or something more specific?

We used Cheezels. Scary to see how much oil actually seeped down the side of the alfoil covered corks!

What? The rim or the Scissors?

Is Hyrdophillia like the opposite of rabies?

Hey Guys, In light of recent new events, we have added in a variation to Nicky's "Who Spread the Disease" prac, which works really well! :clap3: Gotta love it when an experiment variation does work first time! We do two trials. In trial #1 we use 0.1M NaOH, and phenolphthalein, do 3 liquid...

It's been addressed somewhere else here, but basically it goes like this: MnO2 on its own is considered a "naughty" these days. However, it is possible to make cute little MnO2 pellets by mixing 1 teaspoon of MnO2 and 1 teaspoon of Plaster of Paris in a little 100ml takeaway container, wit...

What that means is that if perchance you have a mystery source of Elodia, just tip it all onto paper towel at the end of the experiment and let it dry out and die. Then bin it - rather than tipping leaves etc down the sink. Its the same up here when cane toads mysteriously pass away and we do autops...

Yep - although fine pepper can work too.

The red totes are actually Gratnells. We have 6 and they just slot into my Gratnells trolley beautifully.

Lycopodium can be used like a type of flash powder. Chuck a teaspoonful into a campfire and it flashes and crackles like a magic trick. We used to aerate a little pile of it inside a tin with a lit candle (by using a length of aquarium hose), and it would flash and blow the lid off the can. You can ...

Now what will I do in a cyclone?? They are still a standard part of everybody's cyclone kit!

Found an address in England:

Sensitised Coatings, Bergen Way, North Lynn Industrial Estate, Kings Lynn, Norfolk, England PE30 2JL.

According to a blog I just read its the only place to get it now.

Can't see that there's much difference between a side-arm test tube, and one with bent glass in the top, except, as Adrianna says, lack of durability in the bent glass bizzos.

Worth a try, but will it set?
