Haha, not monetary profit 
I just mean any reactions where you can collect products.

Today I tried to make a Silver Mirror.
It did go quite well, only I ended up with chunky silver precipitate instead of the actual mirror.
But, I made elemental silver out of silver nitrate.

Indeed it is. Where'd you get your silver nitrate?
I recently made Fehling's solution, and a LOT of Zinc Carbonate.

It was in a bottle here at school. I guess my coworker ordered it from a webshop, which I know always has good products. I doubt that silver nitrate
was the problem.

Oh, I wasn't blaming any problems on anything.
I was just curious where you got it or if you used your school's chemicals.
Regardless, elemental silver is nice! Do you have an element collection?

I've been tediously doing runs of benzene synthesis from benzoic acid and calcium oxide as well as trying different combinations of reactants (calcium
hydroxide, sodium hydroxide, etc). Building the set up was easy, just takes a while to get decent amounts of benzene when each run produces about 30ml
of crude benzene, soon will be time to dry and redistill.

Been working on synthesizing molecular motors. I am about to start actual lab prep of the reagents in a couple weeks.
I have also made big steps on my ultrasonic levitation device. I ran the first successful test of it last weakened. Still have big steps to go, but at
least it looks promising.
Also, as a side project, I am working on Aga's nitric acid challenge!

I'm trying to scrape together a driver circuit for my jury-rigged gas proportional counter spectrometer. I've been trying to avoid buying things
online because I wanted to do it in the spirit of a hardware store and scrapyard style build but my city seems to have no electronics stores that sell
discrete components (Which is why that thread went silent). There is a Radio Shack, but they're only selling the most basic stuff and for a ridiculous
markup.

Was your test tube clean and smooth? I think it should be for a good mirror. This is just a guess though.

Total lab overhaul! Split the lab into two buildings as I now have some seriously cool equipment, I decided to have the fume hood and anything thats
not too kind to electronics in one building and the other things in another. Eventually I will get it all sorted properly! So I now have a HP GC with
FID and MS, also managed to get a real bargain centrifuge!! Listed on ebay as non working, phoned the guy up and and got it for £42.
It arrived today and I plugged it in, nothing!!! totally dead, then I realised that the settings switch wasnt set right. I set the controls properly
and off it went WEEEEEEEeeeeeeeeeeee.
So I now have a fully functional centrifuge. Mostly working on yeast at the moment and trying to learn chemistry!
Dont ask me, I only know enough to be dangerous

You have a centrifuge that works on yeast !?!
Wow. That *is* eco-friendly

I think it was. It was brand new. Maybe I heated it too much/too long? Is that possible?

My Tollen's test procedure says nothing about heating. It does say the test tube should be clean.
My procedure for making the Tollen's reagent says that upon standing or heating it deposits a black precipitate which is explosive.
 This refers to the reagent with NaOH added for extra sensitivity.

Ha you mock me now......... we run on generators mostly here so yes in the future the generator my well run on ethanol from yeast  .
Yeah yeah yeah I know its illegal to distill etc etc etc. I will be breaking the law and someone nosey will grass me up etc etc. YAWNNNNNnnnn

Woelen's instructions and Nurdrage's instructions both say you should heat it up to roughly 60 degrees C. So that's what I did.
The initial precipitate was brown, and after heating grey. So not black and hopefully not explosive.

Please read this:

Fresh and spent Tollens' reaction solutions are potentially very dangerous, if you didn't know that already...
You really don't have to get to see the black crystals of Ag3N for such a solution to actually detonate.

I didn't leave he solution to stand for so long. I prepared everything up front so I would be done asap. Everything was done and also neutralized with
HCl within the hour.I did that because I knew the leftover mix would become explosive. Imo I was well prepared and as much as possible risk free.

What have I been doing?
Diet coke and Mentos with the daughter.
Apart from bubble nucleation I don't know the science. I gather that the combination of these two particular products alters the surface properties in
a favourable fashion.
But it was fun!

Been working on graduate school applications.
Aside from that, I've got the hard-ware for my syringe pump about finished waiting on some resistors to do the electronics then then
programming(interface).
Making small amounts of progress on my lithography device but that's going to be another longer term project.
Thinking about ways to over-haul my polarimeter design...
Did a quick synthesis of a cyclodextrin derivative the other day, going to probably do another synthesis of a 3 membered heterocycle in the near
future.
Lot's to do, so little time.
