Wow, that is really amazing! And fascinating how well that scent actually moves through the evolution of a specific kind of fire--- it's not like, "Okay, right now it's doing 'bonfire at Pennsic at midnight' and now it's '4th of July fireworks'" or something else random, it's actually replicating this specific sequence of experiences! (That... seems like the sort of thing the folks at BPAL would actually be trying to do, even if it's not a guarantee because scents interact with our own body chemistry etc.!)
