Is created with dry ice, which used to be the only real way to have smoke or fog onstage.. after the invention of fog machines, which use a concoction of ingredients, the fog would rise and fill the stage, which was a cooler, and easier way to get fog onstage.. after the invention of hazers, who's soul purpose is to put a thin layer of smoke particles in the air (that you can barely see) strictly to highlight the beams of light from the light show, as well as laser beams, which is a super cool effect..
But, if you've ever been engulfed in the fog from dry ice, it is wonderful.. it's so cool and clean and refreshing to breathe in..I could do it all day..
Friendship is like peeing your pants.. Everybody can see it, but only you can feel the warmth..
