Heh... sounds like a good idea for places where frequent false alarms are
placed! (schools, dorms, etc.)

I don't know if that's true, but I did here a somewhat similar story from
my high school chemistry teacher: Their school was having problems with
<somebody> pulling false alarms.  So, they simply coated the pull levers
with <some chemical> (a chemmies can probably say what) that turned the
puller's fingers purple for days!

Apparently they caught the scum who was doing it...
