Re: Iodine Clock Reaction
So linotas, was your solution A clear?
I'm trying another batch but it's not looking good!
My solution B is just 500mls 3% Hydrogen Peroxide and 500mls distilled water

Re: 3 D printers
We had two 3-D printers, but they have just been reassigned to the library.
They weren't being used in science, they do take a long time to produce a figure, so it's not practical to attempt a class set of any figures.
I don't recall what brands they were though.

Re: PERFORMANCE AND DEVELOPMENT PLANS
The SAM is my supervisor here. We were given the forms to fill out and pretty much left to our own devices...... Not a whole lot of support here, and if I ask I feel like I'm being a nuisance! So I wrote what I thought was relevant for me..........

Potassium Permanganate
Hi all,
I need to make up some potassium permanganate, I have my printout for solutions that I got off this site and it says to "filter through glass wool".
Any other way of filtering it???????????????
Guidance will be much appreciated
