Supermarket Chemistry

Hello..... fellow internet users!

I'm a final year Chemist now. Hooray! Erk... Okay. Maybe not that happy :)

Anyway, at most times, a final year chemist in Bristol uni will be given options on whether to choose a lab-based project, or a school-based project. I've chosen the latter one, and surprisingly got it (despite of my poor results).

Now that that's settled, my supervisor (the all-capable Tim) had asked us to create 3 experiments (not 1, but 3) based on the GCSE Chemistry designed for South African's students using basic materials and apparatus found in any South African's Tesco. So, in one way or another, we'll be published in a booklet (at least) for South African's students' practicals. Yay! (You may clap your hands here)

Tim had called this particular part of our dissertation as "Supermarket Chemistry". Splendid name! Don't you think so? 

During this past few weeks, I had a little go in brainstorming ideas for my experiments, and actually came up with a number of ideas:

1) Producing musical notes with different amount of water in glass jars
2) Determining a hard-boiled egg from a raw egg
3) Mixing oil with water

Sadly, I was told to think CHEMISTRY, instead of PHYSICS. I wonder.....

Now, I've thought of a few other experiments that can be done:

1) Making pH indicator using red cabbage
2) Pushing peppers toward the edge of the water surface using detergent
3) Making radioactive looking slime
4) Producing a tube of liquids' layers (colorful, of course)

At a glance, they sounds fun, easy, and cheap enough to do. However, I've got to put more brain into this work. It's only October! Plenty of time.... (as if!)
