Getting tinder started with a match/Bic/whatever, and keeping the kindling and fuel burning when all is wet are two different things. I tried to start a fire once (many years back) in very wet conditions and as soon as the gallon of gas burned off everything burned out, rather quickly too. That wasn't a camp fire and nothing critical was hanging on having a fire so failure was no big deal, but it was interesting to watch the fuel put the fire out; that pile of wet wood was never going to sustain a fire on its own.

Anything that helps keep a small fire burning initially is worth trying. Blowing directly puts your face too close to the fire or far enough out that it isn't as effective. A straw or bellows of some type that can put gentle airflow precisely where it's needed is an excellent tool. I'm not sure this collapsible straw will find its way into my kit, but another straw might or I may take a short piece of metal tubing along. Only the part near the flame needs to be metal. A cheap plastic straw that weighs nothing may be all that's required. Gee, those come in water bottles. Time to experiment.
