You will find that using plastic to hold the CA adhesive drop will result in
a longer "pot-life", as the glass tends to acquire a very thin layer of water
when exposed to anything besides *very* dry air.

Exhaling on the joint before or after applying the adhesive will also hasten
the set-up time. The kicker is just an aliphatic (i.e. organic) mono or diamine,
which, having a fairly loose hydrogen on the amine group, works the same as
water, or possibly better.

Yep, also good if you cut yourself - hold the cut together, and apply a little
CA to the wound. Seals it right up.
