My only recommendation is to start your projects earlier.

But I'd love to make a couple suggestions:

- Illegal Drug-Making
lots of so called 'precursors' - the chemicals one uses to make illegal drugs - are organic halides!  Check 'em out: http://www.safety.uwa.edu.au/policies/illicit_drug_precursor_schedule

- Bombmaking
No details included here...it's not cool to make bombs.  But chlorides are popular for that.

And possibly the most important:
- Killing stuff
Insects, plants, rodents, molluscs, or birds!  You want it dead, there's a halogenated chemical that will do the job for you.  Check out some examples: http://en.wikipedia.org/wiki/Avicide
