Raw mind training, evoking an urge whenever a person is alone and idle.
Simple commercials. A black screen and...

The characters used are various sterotypical characters with amiable expressions. Sexy babe, grandmotherly type, warm-grinning blue-collar worker, anyone it's difficult not to like. Anyone who the eye is drawn to for examination for a few moments.

The only motion in the frame, and the only red object, is the coke can.
About thirty seconds worth.
After several exposures, the Coke commercial is evoked on cue. Footsteps, ticking clocks, any droning and unexciting noise in an otherwise silent space will evoke the thought of Coke and the warm image associated.
