Yes, something like that. The professor who I worked for previously teaches "chemistry safety" classes where
he also teaches from explosives, poisons, ect. The good part is, he demonstrates a lot thing. More: http://labphoto.tumblr.com/tagged/explosive
Another interesting experiment was generating some phosphine.
In the round bottom flask some white phosphorous is melt under a sodium-hydroxide solution and the phosphine/diphosphane what is generated from this
mixture is blown out from the gas phase using some argon.
The gas is bubbled through water and when it contacts with air, it ignites due the diphospane content. -do not try this at home(;
I have a blog where I post my pictures from my work: http://labphoto.tumblr.com/
-Pictures from chemistry, check it out(:

I thought this produced sodium hypophosphite?

It does. It's a disproportionation. Phosphorus is both oxidized to hypophosphite and reduced to phosphine in a redox-balanced manner.

Copper Acetate synthesis:
Some coiled telephone wire in a test tube filled with glacial Acetic Acid. After 3 days at room temperature, the solution is a nice sharp cyan color.
A previous synthesis yielded some very nice 1/2mm dark blue crystals.

My brother is into photography and recently built a diffuser for his flash to use for macro photography. I found him a subject in my jar of
1,3,5-trioxane while I was reorganizing my lab space.
EDIT: attached a large sized version for anyone who wants it.

Quick follow-up to last week's experiment:
You can already see the formation of Copper Acetate crystals on the surface of the copper wire coil

looks nice, will try soon and post some macro photos.
... some copper sulphate crystals ( you can find 4 more photos of one big copper sulphate monocrystal here copper sulphate monocrystal)

Fun with fluorescent dyes. Here I used fluorescein-isothiocyanate, rhodamine 6g, aesculin and eosine(:

Here is terbium (actually ferroterbium) taking a bath in HCl. The sample I received was contaminated with iron, and I'm attempting to determine the
purity of the source material.
The second photo is some magnesium I burned. For the last two New Year's Eves I've burned magnesium. This may be the start of a new tradition.
The third photo is a mixture of red lettuce pigments separated through chromatography. Fun lab. Unfortunately the pigments faded away after a few
weeks.
 
At the end of the day, simulating atoms doesn't beat working with the real things...

I know there has already been a post on copper sulfate crystals, but I thought I should add this.
You should open the file to full size, it is much better.
Here are the specifications:
Camera: Canon 60D
Focal Length: 55mm
Aperture: f/5.6
Shutter Speed: 1/100 sec
ISO: 100
Flash: None

My phenol usually arrives as small loose crystals but this time the supplier poured it liquid into the bottle and I was pleased to see a shiny solid
250g mass when opened  never seen large phenol crystals in person
Pic is not as nice as UC's previous phenol though

Not the best shot ever, but these hydroxylammonium chloride crystals won't cooperate with my camera. I made them in a few rather annoying steps from
sodium nitrite. I'd be more annoyed if there wasn't 400mmol in the picture because that should be plenty for my needs.

Gold refined from a chain somebody was throwing away because it was ugly... Managed to get 2.85g from the 14 carat item. So got about 125$ worth of
gold for free

Mailinmypocket: Nice! I'd be interested to hear about your procedure; sounds like a fun experiment. What's the (ballpark) purity of
your recovered gold?
