On a recent trip to a place where a lot of people seem to smoke, I noticed that many of these smokers, when finished with their smoke, hold the cigarette butt between their middle finger and their thumb and flick the butt with their index finger as far as they can, usually over some obstacle like a fence or out a car window or what-have-you. I don't really know why they do this, but they do.

The observed failure rate of these flickings is fairly high as, usually, the butt doesn't travel very far before wind or air resistance overcomes the lightweight cigarette butt causing it to fall short of the smoker's intended target.

Butt flicking clay, then, adds substantial mass to cigarette butts allowing them to be flicked far greater distances and with significantly greater accuracy. Each package of cigarettes includes 8 or 10 high-density butt flicking clay strips that the smoker can wrap about the cigarette butt prior to flicking. Additional premium grade strips can be sold separately for those who want a strip for each butt.

(This idea she posted shortly after a family trip to Africa.)
