PART 1 - SENSES AND SCIENCE AROUND THE CAMPFIRE

Sight... 

From my experience it is the sense most stimulated when watching a campfire... 

Just sitting and watching, as the flames of the fire dance around like little ballerinas running around wildly on a stage. Watching how the fire causes thin twigs to twist and turn, and eventually end as ashes. The more I get drawn in watching, the slower the flames dance and the slower the wood dies. I can sit there memorised.

My question today is, what happens when we are seeing?
