Do you remember the old photographic flash bulbs? They may not
reach the same peak brightness as an electronic flash, but they burn a

with the blue blobs floating where the bulb was in your field of vue
when it went off. :-)

And when gently cracked and then placed in or above above a container of
a flammable substance..make very nice and very positive ignitors.

Hmm ... *that* I didn't know.

But did you know that if you placed one or more flashbulbs in
contact with the one which you are about to fire, those will go off at
the same time (or at least close enough so you could not tell the
difference without a scope and a photovoltaic sensor. :-)

And -- if you got them close enough to radar (e.g. at an
airport) they were likely to go off as the radar beam scanned past? A
good thing to wrap your spares in aluminum foil if you were going to be
closer to the radar antenna than the typical passenger.

Enjoy,
