Thanks Judy - I have checked the pop up blocker.... will have to get our IT guy on it. He's part time so have to wait... grrrrrrrrrrrr!

Thanks guys!

We let the kids use wire loops for the FeCl3. Gives them practice!! And shows them there are different ways of doing flame tests.

Will let you know - going off to pull them out of the hot water & then use the HCl......

Hi Maria, I can't even get it to come up to put my username / password in! It just keeps trying to get there....

I think all the single use instant cold packs are ammonium nitrate... Ours was an unused one - we didn't rupture the inner liquid pouch - just opened it & kept the round granules of the ammonium nitrate. Naughty :redcard: ............. but cool! :thumbup: Better still - do the exothermic / endot...

Hi Everyone, Hope you're all having a wonderful day so far! A teacher recently put copper carbonate in my flame test aerosols & it has clogged up the pump bits. I've tried soaking them in cold & hot water but only helps a tiny bit.... does anyone know how I can clean them out? Another chemic...

They are great Sammy! I hope you find some - our kids adored our sole male.... til I found him on the bottom of the cage. Poor Egbert RIP...

Thanks Lada

Hi Everyone, Was wondering if any kind labbie out there would have some spare Stick Insect eggs or any other insect for that matter - would love rhino beetles too!?! Not sure that the rhinos come via eggs?! Only one of my last lot hatched & he died recently... RIP Egbert Stickbert :cry2: ..........

Hi Kay, no only use fishing line in place of sailors line....!

Flame tests - we use solutions in aerosols & wire loops for some chemicals that don't like going in the aerosol bottles.

Cheers Kel

One of out teachers tore open a cool pack - full of ammonium nitrate. ... so much for trying to stop Al-queda!!!!!!!!!

Hi Rell, I'm in Vic too but couldn't find anything on dry ice. We recently had a yr 8 teacher do dry ice to make icecream. I decided that all I could do was warn & make sure they did the risk assessment appropriately. They are supposed to be trained & be safety conscious. I have a work book ...

So glad the ringing has stopped Noona! And wishing you all the best for a great hearing test later on.

At the risk of insulting tradies.......... Is plumbers line the same as plumbers crack??! :cheesy: :cheesy: :cheesy: We use fishing line in our lab. Sooooooo much fun coming up - my fave time of the year - flame tests!!!!!! YAYAYAYAYAYAY Just wanted to share my joy & good mood. :thumbup:

Thanks Kathryn & you others! I've been waiting to see what you clever lot would come up with. When I finally get my hands on some white flowers I'm going to have a try too! Cecmel - I saw that one with the tissues & indicators too... sounds good in theory but I agree with you.. messy! I wond...

OMG Shame on you Smiley!!!!!!! :redcard: :redcard: Those poor innocent children surrounded by bombs & you forgot their hats. What will their parents say when you send them home with a sunburnt head..... I'm sure they'll all just ignore the missing arm....! Having said all that rather dripping wi...

Hope all is ok now Noona.

We don't do that demo - probably a good reason not to!!
Having said that though - do you actually do an exploding day Smiley??? What do you do??

Is to keep the natural selection happening at your school?!!! Keep those little tulips in line??

Sounds cool cecmel! I don't know anything about it but what you're doing sounds like good!

I look forward to the answers too!

Oh phew! Thanks Wendy! I thought it meant all the normal sciences - chem / biol etc... too! THat's currently what i'm studying to teach!! Freak me out or what! Thought I was being made redundant before I even started!!!

Cool Estelle! Will remember that - I put mine in the fridge in their containers but they must have some air leaks..... will wrap em up next time!

Wow thanks Judygee! You were so kind & quick! Really appreciate it!!

Much karma coming your way
