Successful experiments
I think there should be a thread on the successful experiments that are done here.
I'll start.
Today (27-1-2014) I extracted lithium from a lithium battery, I've tried at least twice before, and this is the only time it worked.

i always end up with the lithium oxidizing before i can get the casing off, how did you manage to do it?

It oxidized a little, but I put it in a CO2 (not really inert, but better than air I'm sure) filled vile before much happened.
With the first battery it failed considerably, I just took way to long taking it out, the second time however, I took the pliers and yanked the roll
out of the steel casing, without striping the casing at all, I was really surprised at how well it worked.
It was not a energizer ultimate lithium battery, it was a duracell battery.

I recently sodium via sodium hydroxide and it worked much better than I had expected. This will be the 32nd element in my collection!

I have yet to even try that, I don't have NaOH at the moment, I've always thought that an complex setup is needed, to keep air out and whatnot.

While congratulating you with your success, I think the topic of this thread is too unspecific.

Zyklomd, the procedure is actually very simple and the one I used is a variation of this.
Everything except the magnesium can be sourced from your local homedepot.

Thanks, I intended it to be for success in general, isolating elements, making compounds, ect. Not necessarily for everybody who has a successful
experiment of course.
There are topics for bad days in the lab, chemist's nightmare and other bad things, why not something for good things?

@Pinkhippo11, I assumed that you meant you did electrolysis of sodium hydroxide, I have seen that video before but I though the sodium quality would
be very bad (contaminated). I can get NaOH, I just don't have it right now.
I guess I will try it now that you said it worked well.

Yes, the quality is not exceptional, but I too do not have the equipment to preform such an electrolysis. However, the purification methods in the
video are surprisingly effective and do not waste very much sodium metal. Give it a try if you don't have access to sodium metal, it is very useful.

Did you try any methods other than those shown in the video to purify you product? (sodium)

Personally, when I tried this methode 1° It was an horrible pain in the  to make
a good quantity of magnesium powder from a magnesium fire starter 2° It produced some sodium mixed with some crap but it did not survive the
oil/water purification. The fact that I used a fire starter and NaOH from drain cleaner probably mixed with other things instead of pure NaOH may be
the cause of the failure, but in the futur there is no doubt I will buy the sodium instead.
You can also see from the video that the sodium produced is quite a good step less reactive than pure sodium.
I must however say that the reaction was quite nice, surprisingly powerful. I was glad I put a concrete block on top of the lid.

Here some people talked about using Al instead of Mg, I will try this as soon as I get some NaOH.
Al will react with NaOH because it's amphoteric, but if I can light it quickly it may work.

Give me some news, It's been a while since I did it, I now have pure NaOH and Al powder so I might give it a try if it works.

Or: Mix 20g powdered aluminum, 6g NaOH, 3g NaCO3, and 5g NaCl in a steel crucible.
Put the crucible over a heat resistant base that allows heating by flame. Cover the crucible with a steel bowl filled with water.
Heat the crucible vigorously with a blowtorch or a heavy duty bunsen burner until a reaction takes place, marked by yellow flames escaping from the
crucible.
When the reaction is over and the crucible is no longer red, remove the bowl carefully pouring the water away. There should be a light grey deposit at
the botton. Scrape this deposit with a spatula to a 50ml vial with some xylene in it using a funnel. Repeat this procedure four times.

Such a thin film of sodium would react very quickly with air and moisture, I would think. Also you'd really have to heat this thing to reach the
boiling point of sodium (unless the reaction is exothermic enough, I suppose).
What's the reaction equation for this process?

The reaction is definitely exothermic enough, it's sometimes classified as a thermite reaction.
You can read all about this (and similar reactions) here.
This is getting rather off topic... Further discussion of such things should be continued here as well.

Did a nice small scale synthesis this week, phthalic anhydride to anthranillic acid to methyl red. Might make a post on it with pictures and what not
in the next week or so.

I made about 8 grams of CuCO3 yesterday, it's very bright, rich blue-green color, I'm very impressed.

I made cis-bis(glycinato)copper(II) the other day. The reactants combined to give a glorious dark purple-blue solution (much like
tetraamminecopper(II)), but as it cooled, light powder blue needles started forming, eventually turning the entire solution into a semi-solid mass.
This filtered out to a pale blue powder. Actually disappointing.

Huh, that's too bad, I've had similar disappointments, where it looked like a great product, but it turned out to be rather bland or boring.

Today I isolated a lot more lithium from a lithium battery. Yields were even better than last time, I might make a guide on how to do it. The
batteries that I used are much easier to extract than energizer ultimate lithium batteries.

Today I made some I2Cl6.
I also plan on making more from direct reaction of I2 and Cl2, as opposed to the method that I used this time.
[EDIT] Well, of course it didn't last very long, It gave off chlorine as it formed iodine monochloride, which in turn, evaporated, leaving nothing to
remember all my work...
Oh, well.
Recently I've been trying to make lots of covalent Cl- compounds. I plan on making ICl (iodine monochloride), and a few sulfur chlorides
too.

Extraction of Lithium from batteries: http://spatulatzar.com/lithium/
My advice would be to do the whole process with the battery submerged in mineral oil, like in a large bowl or bucket, if oxidation is such a major
issue.
