Sauron, I think your message is clear. There are more efficient methods of making Cl2 than using KMnO4, but sometimes there are other things as well
(such as having the chem at hand, making small amounts, etc.). The question here is not how to make chlorine, but what kind of interesting experiments
can be done with it.
I can add one other interesting experiment, provided you have calcium carbide (a.k.a. "carbid"). Make some chlorine gas and put this in a beaker,
upside down under water. Make some acetylene gas with the carbide and carefully bubble SMALL amounts into the chlorine gas. Each time, when a bubble
of acetylene goes into the chlorine, there is a flash and a bumping noise. Quite spectacular. I have done this experiment myself and it is spectacular
and can be done easily.

woelen, I am annoyed with this tyro's attitude. Read his ither thread and you will see, he literally doesn't know how to pour piss from a boot when
the instructions are carved into the sole.
He was ass-backwards on how to make Cl2 from his own chosen reagents.
This is someone who neds to read more and post less.

Well, anyway, I am in no pocession of calcium carbide, but I will keep an eye out for it.
Like woolen said, this isn't about the production of chlorine, it's about the uses of it.

Another VERY nice experiment is burning sodium metal in chlorine gas.
Use a spoon-like spatula, and put a SMALL piece (50mg is enough) of sodium on it. Have a large heat resistant flask filled with chlorine gas at hand.
Heat the sodium with a burner. First it will melt, but not ignite. At some point the molten metal will be visible and it will ignite. Now carefully
lower the spatula in the chlorine filled flask. It burn with a VERY INTENSE yellow flame, your eyes will hurt. It's amazing.
Do not drop it on the bottom of the flask, as it might shatter. If you do, first put some sand or NaCl in the flask to absord the heat.
Be careful, the smoke evolved when the sodium still burns in oxygen is very corrosive to your respiratory tract (it's sodium peroxide).

Yes indeed burning sodium in chlorine is very nice! Woelen I like your page on this experiment, would make a lovely demonstration to young students
wouldn't it?!
Just trying to think of other experiments. S2Cl2 is obvious as is ICl / ICl3 all on small scales (especially the sulphur one)
Making AlCl3 or FeCl3 would be nice (and usefull) from aluminium foil or iron wool respetively.
P.S.
Just a thought but if anybody lacks sodium perhaps something similar with lithium foil from batteries could be used?!

Is blindedachievement in USA? If so he is unlikely to acquire any I2. So making ICl or ICl2 is a non-starter.

chlorine
i think back to my chlorine experiments with bad memories. I tried to do an organic chlorination with UV lights. My lab stunk for months and I had
to throw out my clothes for three days. The washer wouldn't remove the smell.

Last week I went to the pool and forgot to wash my shorts over the weekend! After a wash with my favorite brand washing powder I can still smell the
chlorine! Dam sports centre!!! 
But to fumigate a garage with chlorine enough to stink it out for months?.... I'd be a little worried about the state of your lungs bluemike!!!

Swimming in chlorine-sterilised pools doesn't do your skin any favours either.

Another easy reaction is to take the chlorine gas and bubble it through a solution of sodium hydroxide. You wind up with what is basically chlorine
bleach!

Ahh a use of chlorine?
How about formation of the singlet oxygen it exhibits red chemiluminescence.
You can do this by bubbling chlorine gas into a strong solution of sodium hydroxide and hydrogen peroxide.
Now for you to understand the full meaning of the singlet oxygen...thats a different story. A lot of math and physics.

Perhaps he meant the smell was of some toxic, carcinogenic organic chemical he produced instead of the chlorine gas that was stinking up the garage.

As an alternative to a fume hood, the hydroxide + chlorine -> hypochlorite reaction can function as a chlorine scrubber.
I was using a continuous stream of Cl2 for something recently and needed to do it inside--where I have no fume hood.
Using an erlenmeyer flask as the reaction vessel(instead of a beaker) I was able to feed the unused chlorine gas into a large flask of concentrated
sodium hydroxide.
I successfully completed the reaction without anything more than a faint chlorine smell. The smell was closer to hypochlorite than chlorine gas
anyway.

Make sure you don't get suck back with bubbling chlorine into Sodium Hydroxide. I'm not to sure it could happen as I've never bubbled chlorine into a
conc. NaOH solution but it seems like it could easily happen and result in some serious problems especially if the NaOH soln. hit some acid.

You can avoid suck-back problems by having an empty bottle with a 2-holed cork between the chlorine generator and the NaOH-trap. If NaOH solution
sucks back, then it first fills the empty bottle and then you have enough time to unplug the inlet of that bottle.
