I think we start out project next week, although what it is is still a mystery... This is the first year our school has required us to show up after the ap test, had I done this class last year (accursed counselors that wouldn't let a freshman into ap chem) I wouldn't have had to show up unti 9
In any case... There is always nylon... Sorta easy though...
A assume they wont let you do anything that goes bang?
Perhaps electrolysing something fun, like NaOH?
Could you do the aspirin synthesis, or did you already do that?
Something to do with equilibrium? Like the NO2/N2O4?

I need a topic for my project, I was thinking of some sort of synthesis, polyesther or something.. Any ideas?
Well, I can tell you that polyester (I assume you mean the resin?) is not all that easy to synthesize. I have made quite a few resins, and they require high temps for long times, and there is also a distillate that will be generated, and of course you have to be very careful that you stop it the right time or you can end up with a solid chunk of resin in your cooker, never to be removed.
Nylon tends to get frowned upon because one of the ingredients is extremely toxic.
Are you sure you want to do a synthesis? Why don't you try something simpler, but gets amazing reactions from people, and that is ferrofluid.
Look for the ferrofluid threads and there is a link to a very nice detailed synthesis.

I don't think making nylon is pathetic at all, in fact it's an amazing demonstration if you can get an interface between the two liquids and wind a good amount of polymer out of this interface. I just worry that everone has seen it, but not everone has seen ferrofluid, and I have asked some of my fellow engineers about it and they have never heard of it.
Here is a pdf for the best synthesis document I have found. My Acrobat Reader is not working right now so I apologize if this is the wrong link.

Not that Nylon wouldn't work, but how 'bout something even more impressive, that they likely haven't seen-- gemstones! The Flame Fusion process, at least on paper, seems simple enough: silicon (for quartz) or aluminum oxide (for corundrum) dust is finely drizzled through a flame or electric arc, melting it. It's then pooled on a rotating earthenware rod, and voila! Crystal. OK, so you're not reacting anything with anything else, but crystalization is still in the relms of chemistry, last I checked, and I'm not sure if the process can go fast enough to make any kind of meaningful demo, but I thought I'd toss it out there. I aim to give this one a shot myself ('s the only way, I suspect, my luv will accept synthetic gems )
Knowing it's for AP-chem from the first thread does not give non-American readers much of a clue what AP-chem actually IS, mind you. Senior level High School? Advanced Placement? Sure, we could google it... but a little background never hurt any, either.
