Congratulations! A new apprentice Chemtalker on the way! How lovely!

Hydrilla is similar to Elodea.

Hi Lada,

We incubate it for a few days but we use ham or other processed meat. I do not think rotting fresh meat is OH&S friendly for several reasons.

AND (according to my son when he was very little) we had to fight the dinosaurs off!

That is sad, but you were a winner to get there! Think of all those schools that didn't even make it to the nationals...Congratulations on your (the school's) effort!

Now, now children! Play nice...

Congratulations to both your schools, it's obvious they have achieved due to the superior service you both provide!

Me too. I hope all Okay. I have family at Hamlyn Terrace which is near Warnervale. I am thinking of all who live near the fire fronts.

Hey Graham,
I was wondering if you know why it's not safe to autoclave parafilm. I autoclave the diposable petri dishes, tape and all before I dispose of them in the garbage. Should I stop doing that?
regards,

Thank goodness for the diagram!

I haven't had any problems with just putting 1g of powdered phth in my phth agar. Colour has been the least of my problems... my problems always stem around operator error!

Happy Birthday Smiley! Hope your day (and year) is gr8!

Woo Hoo! Congratulations!

I remember someone said here that they don't try to listen for the bell when the pump is on, but listens to hear the bell when they can after the pump is turned off. Rather what Smiley said in her post. I thought it's a rather clever twist on the experiment!

We have been nut free since 2007 and trained in epipen usage. Narelle, it's a shame people just don't take notice of no eating or drinking signs, they have no idea that it can go beyond looking after the venue. Shame on these obviously "illiterate" people.

Hve you managed to erradicate ALL nuts? Or are there several under surveillance...

Thanks Graham! Now I'm that I didn't look further! Happy Easter everyone!

Oh Rosalie!
Where is the "little green with envy smilie" when you need it!

Noona,
It's already been shown but if you go to the ABC iview internet site you can watch it! The program will be available to watch for another 12 days. Interesting stuff about the formation of Hawaii and the volcanoes!

Wow! Hawaii sounds much more exciting than the Central Coast. I am going to visit my mum and brother and my girlfriend whom I have known since I was 5 (that was just after the dinosaurs died out!). Enjoy Hawaii and don't forget to share lots of photos! - check out the show HOW THE EARTH WAS MADE on ...
