Not exactly ground breaking info. This kind of technique has been around for a long time. At least as long as I can remember, and I am closing in on 52.

But its a pretty basic kind of thing to have available, and not a bad thing to bring it up now and then.

I think a lot of people have no idea how easily common things like cotton balls, dryer lint, or TP can be ignited to get a fire started.

Adding the PJ is nice because it burns a lot longer and hotter then just the cotton ball, giving you time to get a fire going.

Personally I am kind of a fan of having the PJ in a container of its own, rather than premixing it into the cotton balls.
