What are the rest of you's planning doing?

To do this I've needed to make my own gas chromatography (very tricky) and I'm in the middle of passing alkenes through it - alchols are a liquid and cant be done so just dehydrate them and you get an alkene...apparently. After that I'm sure that theres at least another 10,000 things that can go wrong but hey...thats chemistry!
The other people in my class are doing:
Synthesis of Aspirn
Testing of minerals in water
Just for some ideas

We had a few laughs about it, and telling us things not to try, lol
"...things like investigating the boiling temperature of water!..."
I have no idea of what im gonna do for mine.

My investigation starts tomorrow. I am going to be testing to see if aspirin help to transport Cu(II) ions across a simple membrane.
It has been suggested that I use visking tubing for the membrane, but anyone that does biology will back me up in saying that there is many other ways of crossing membranes.
Anyway, I think it should be quite interesting - plenty of things that can go wrong tho!
When is everyone else starting theirs?

Degree of unsaturation in oils - using Iodine number method
Analysis of commercial aspirin tablets
Sulphur dioxide content of white wine
Vitamin C extraction from Green vegetables (yawn!)
Fermentation - takes ages - need to have 2 fermenters set up at a time..
Growing crystals - Liesegang rings (need about 1 month!)

Hi, I'm doing my investigation on this as well but am unsure how you are meant to measure whether it has helped or not. Presume you do some measure of conc but what? titration? precipitation? colorimetry? ...
