With Sulfuric Acid or Sodium bisulfate are also nice prospects.

Are brewery supply shops and/or health supplement stores fair game?

oh yeah. Sodium metabisulfite, whey
powder and choline chloride. There's some possibilities there.
Back soon.

@aga
You know, the competition runs for a while. You might change your mind. Circumstances may change. I'd love to have you throw your hand in.
Or contribute some prize money. That's pretty cool too. The available loot here is creeping upwards. I will get back to you on that one. If we
have many participants there might be reason to award second and third places.
@zts
Photographic stores I think will be ok. I mentioned them in the rules. But if your item comes from a photographic store and has no significant use
in photography, then I think that steps over a line.
@MolecularWorld
I think it might be possible to be a bit pedantic on moving parts. I would not want to exclude something of the nature of a screw-top lid or a
spring. One could even argue that a gas has many moving parts. I would allow an iron with a couple of switches and solenoids. Hopefully this does
not open up realms of confusion. If anyone has a serious question on the matter, just ask.
As of aga's offer, the prize pool is 100USD, 50EUD and a package from woelen.
Counting U2Us and posts in this thread, there are 9-10 individuals that have indicated an interest in entering. Where they have been disclosed, the
ideas have been really diverse and roughly split between organic and inorganic.
I can't wait to see them all come in.

Depending on other pointless distractions (work, life etc) i may well have a bash at this.
Sounds like good fun almost anyone can have a go at.
The €50 is there either way.
(it's Euros, not Euro Dollars - Yet ! )

Here in Russia we have the KROT brand of drain openers. It is a mixture of sodium hydroxide, sodium sulfate and sodium chloride. The hydroxide is in
pellets, and the other two as fine powder, so you can easily separate the hydroxide with gauze cloth. I will definitely use this one, it can give me
three chemicals for the price of one: sodium hydroxide, hydrochloric acid and sodium bisulfate.
Smells like ammonia....

The different kinds of drain openers available in different parts of the world has been something of an unexpected revelation. I have not encountered
that particular mix before. Sounds like a good choice!

I think I already know my list of OTC items:
1. The Bat
2. Saltpeter (potassium nitrate, fertilizer)
3. KROT
4. Bleach
5. Nails. Ordinary carpenter's nails. Ferrum.
Two very interesting experiments can be done with nails. One is making ferric sulfate and its decomposition to make SO3. Another is an experimental
KOH-less method of preparing potassium ferrate.
Smells like ammonia....

It's in the detailed instructions.
Worth a re-read if you need clarification on a few points.

Wow, what an incredible competition! Count me in. The only other one ive been in was the Chemistry Copper Carnival Competition. I'll look at the rules
when I finally get out of bed... What if I do some biology stuff with the
reagents? It'll still be 'experiments'. But I'll be making useful stuff by them.

A packet of yeast counts as an item. Likewise a packet of seeds. If you collect mould from bread, fruitflies from your fruit-bowl or mushrooms from
your lawn, they count as an item.
If you collect a wild yeast from the air, you get that one for free. But it does make it a bit more difficult for others to replicate and so
repeatability may be a issue.

So just to clarify this completely: if you buy one item, say, a paint stripper that contains a few different solvents and then separate it into its
pure compounds, that still only counts as one item?

I'm having trouble with my Word Document. When I inserted the pictures of the first few stages of my procedure and then saved and exited,they became
an unrecognizable jumble of pixels when I came back to update it a few days later with some additional notes. I tried scanning my computer with my
antivirus in case an infection was causing the pictures to distort,but it detected nothing. Does anybody have any ideas on how to fix that issue?

What format were the pix in? is it just the pictures that are corrupted or the whole document? If the rest of the document is ok, then I would
simply delete the pictures and try again -- preferably converting to another format first.

Wow, I'm not even close to starting mine yet. Hoping to trial the first step Friday.

Alright,I did a backup on my computer and loading in pictures should be fine now.

Yeah, why not. They won't form part of your final product. And presumably you dry and re-use them -- just like you would a beaker.
