Lead nitrate
I have a large amount of lead nitrate. Many kilos. I bought it before there was a price jack-up a couple of years ago, mainly to feed my efforts at
plating a PbO2 anode for perchlorate electrolysis.
In my usual fashion, I estimated the amount required and multiplied it by some ridiculous factor, so now I have more than I'd ever need in one
enthusiast's lifetime.
The question is simple - I will NOT sell it, so don't ask, but what cool things are possible with lead nitrate? I need to expand my horizons a bit
away from electrochemistry. If someone had 10 kilos of lead nitrate, what would you do with it. 
This is mainly for fun. Suggestions, however weird, are welcome. Go for it!!

make lead oxide and mix with paint and use for antifouling paint, if you happen to have a small boat
slowly poison people you dont like  (just kidding)
how about making elemental lead?
all above information is intellectual property of Pyro.  |

Make a kilogram of lead iodide precipitate in a giant beaker, then put it on youtube with a link to a website on it. Profit!

Lead nitrate solutions are dense like hell! what about making a saturated solution of it so you can levitate in that pool!!

Make PbO2 out of it by adding hypochlorite solution to a hot solution of lead nitrate. Then use the PbO2 as an oxidizer.
Synthesize plumbites and plumbates.
Make organolead compounds (just be especially careful)
Explore the chemistry of lead, just don't get poisoned!

Add Oxalate acid to an aqueous solution of Lead (II) nitrate and make dilute HNO3 and a white precipitate of PbC2O4:
H2C2O4.2H2O + Pb(NO3)2 --> PbC2O4 (s) + 2 HNO3 + 2 H2O
Or, heat the Pb(NO3)2 to generate NO2 (note the crackling noise):
2 Pb(NO3)2 (s) → 2 PbO (s) + 4 NO2 (g) + O2 (g)
You can also thermally decompose the Lead Oxalate (see http://pubs.rsc.org/en/content/articlelanding/1948/jr/jr9480... )
3 Pb(OOC)2 ---> 2 PbO + Pb + 4 CO2 + 2 CO
Per Patent 5252311 (see http://www.google.com/patents/US5252311 ):
"said lead monoxide powder has been produced by heating lead oxalate having a plate-like morphology at a temperature ranging from about 400.degree. C.
to about 600.degree. C. for a period of time sufficient to convert said lead oxalate to said lead monoxide."
The resulting PbO is described by said patent as forming "A phase homogeneous crystalline lead monoxide powder comprising substantially free flowing
massicot lead monoxide having (i) a substantially plate-like morphology, and (ii) an average particle size of about 0.1 to about 10 microns in
diameter as determined by photosedimentation methods, which lead monoxide retains its massicot crystalline form under ambient temperature, pressure
and humidity conditions for a period of at least about 6 months"
Be careful not to be exposed to fumes on heating and when working with this fine PbO dust (serious inhalation hazard).

Some great suggestions! Lead Nitrate is a useful lead salt, for sure.

OK, I'll bite - what is useful or cool about lead iodide? Do some painters want an "authentic" yellow color?
Lead chemistry is very interesting, colorful too. It's a shame that so many of the genuinely colorful salts and solutions are also toxic as hell. Ah
well, I'll figure out something to do with it.
I do have a few liters of waste plating liquor I need to deal with, and want to do so responsibly. It's got mostly lead, but also nickel nitrates,
with a small amount of nitric acid. I'm thinking of dumping in some saturated sulfate salt, like epsom, to at least force the Pb into an insoluble
mass.

It just looks pretty, a classic chemistry demonstration. video. it is also very insoluble

Grow a giant, very heavy single crystal of it.

As an anhydrous nitrate lead nitrate is useful for the generation of N2O4, by heat decomposition.

LOL and then slowly poison yourself while you float peacefully
Still, make some lead iodide (lovely yellow precipitate) or make it anhydrous and oxidise some combustibles! Flash powder maybe?
Or if you're a pyro, you could make lead oxide via the carbonate and make thermite?
You may be able to do some nifty redoxes though.
