Glitter is actually pretty dangerous because of its sharp edges.  People have lost their eyesight because of it.

I was thinking gentian violet and methyl mercaptan.

Or in the US, the MK870 version of the device which features an organic control system.

DHL is known as Drop, Hide, Lose  >:D  Oh, the stories I could tell you about DHL experiences in the US.

Hey! You shall not change contents, whole meaning of citation. I did talk about *German* branch of DHL, not whole company as such:

Hmmm,  I was at a gun show in a large (100,000+ sq foot) convention center.  Some people were selling packages of 6 small (1 ml?) glass ampoules of some stinky,  REALLY stinky,  REALLY REALLY STINKY sulphur compound.  Somebody broke one of the ampoules.  It filled the whole place with super-skunk-stank...  really impressive stuff.    Of course, I bought a package.  I think I know where they are...   >:D

Also, maybe toss in some tellurium.   Google "tellurium breath".  A few micrograms of the stuff will give you super-garlic-breath / body odor for a month.    >:D

Then there are those thiols and selenium compounds that made their way to Derek Lowe's "Things I Won't Work With"  Apparently a few grams can stank up a whole town.   >:D

That was probably methyl mercaptan aka methanethiol or the odorizer they put in natural and propane gas.

John Clark had some things to say about using mercaptains in rocket fuel:

But then Pino, in 1949, made a discovery that can fairly be de-
scribed as revolting. He discovered that butyl mercaptan was very
rapidly hypergolic with mixed acid. This naturally delighted Standard
of California, whose crudes contained large quantities of mercaptans
and sulfides which had to be removed in order to make their gasoline
socially acceptable. So they had drums and drums of mixed butyl
mercaptans, and no use for it. If they could only sell it for rocket fuel
life would indeed be beautiful.

Well, it had two virtues, or maybe three. It was hypergolic with
mixed acid, and it had a rather high density for a fuel. And it wasn't
corrosive. But its performance was below that of a straight hydro-
carbon, and its odor — ! Well, its odor was something to consider.
Intense, pervasive and penetrating, and resembling the stink of an
enraged skunk, but surpassing, by far, the best efforts of the most
vigorous specimen of Mephitis mephitis. It also clings to the clothes and
the skin. But rocketeers are a hardy breed, and the stuff was duly and
successfully fired, although it is rumored that certain rocket mechan-
ics were excluded from their car pools and had to run behind. Ten
years after it was fired at the Naval Air Rocket Test Station — NARTS
— the odor was still noticeable around the test areas. (And at NARTS,
with more zeal than judgment , I actually developed an analysis for it!)

California Research had an extremely posh laboratory at Richmond,
on San Francisco Bay, and that was where Pino started his investiga-
tions. But when he started working on the mercaptans, he and his
accomplices were exiled to a wooden shack out in the boondocks at
least two hundred yards from the main building. Undeterred and
unrepentant , he continued his noisome endeavors, but it is very
much worth noting that their emphasis had changed. His next candi-
dates were not petroleum by-products, nor were they chemicals
which were commercially available. They were synthesized by his
own crew, specifically for fuels. Here, at the very beginning of the
fiO's, the chemists started taking over from the engineers, synthesizing
nc:w propellants (which were frequently entirely new compounds) to
order, instead of being content with items off the shelf.

Anyhow, he came up with the ethyl mercaptal of acetaldehyde and
the ethyl mercaptol of acetone, with the skeleton structures
respectively. The odor of these was not so much skunk-like as garlicky,
the epitome and concentrate of all the back doors of all the bad Greek
restaurants in all the world. And finally he surpassed himself with
something that had a dimethylamino group attached to a mercaptan
sulfur, and whose odor can't, with all the resources of the English
language, even be described. It also drew flies. This was too much,
even for Pino and his unregenerate crew, and they banished it to a
hole in the ground another two hundred yards farther out into the
tule marshes. Some months later, in the dead of night, they surrep-
titiously consigned it to the bottom of San Francisco Bay.

Leaving on the porch has been common practice for a long time, most people are not home during the day when the deliveries come and in most areas people have the decency to not steal something off someone's porch. Unfortunately these thefts have been getting more common in recent years, thankfully I have not personally ever had anything stolen. I have had packages delivered to a house with the same number on the next street over on numerous occasions though and I've received some of their stuff. USPS and UPS mostly.
