If there were a portal through which you could see all of the invisibleair currents, temperature gradients and differences in pressure andcomposition of air,then this is what it would look like to strike a match.This is helium being squeezed out of a balloon.You could see the warm air rising off your hands.The invisible vapors of isopropyl alcohol and a plume of ejected material when you sneeze.This is the setup for how I made those shots over hereI have a 40 centimeter diameter concave parabolic mirror normally this would be used to make a telescopebut if it form, just a tiny piece of a bigspherical shellRight? A giant spherical mirror that we're insidethen the center of that mirror would be right hereAnd that's where I've placed this led it&...
